Family Business and Business Management Essay Example | Topics and Well Written Essays - 1500 words

Family Business and Business Management - Essay Example Many of the world’s leading publicly listed corporations are operating under the category of family business. For instance, corporate giants like Walmart, Samsung Group, Tata Group, and Foxconn are some of the well-known family businesses in the globe.   From the viewpoint of the family business consultant Schneider, there are eight major elements including purpose, structure, organizational culture and relationships rewards to shareholders, potential mechanisms in the organization, leadership, strategic and operational performance outcomes, and financial performance outcomes influencing the development of a healthy family business (para 4). The purpose is the factor determining the existence and long term sustainability of a family business. The major reason for the failure of many family businesses is that there exists ambiguity and lack of agreement on the vision, priorities, and goals of the business. Hence, a healthy family business will be characterized by clearly stated business goals and priorities. In addition, it is commonly seen that many family business ventures do not survive beyond the generation of the founders due to lack of foresightedness. In contrast to this, a strong family business will have a well-defined family philosophy that facilitates the continuation of the business beyond generations and sets a framework for the future operations of the company. According to Schneider, â€Å"structure is the architecture of grouping people in the family business† (para 5). The author continues that the structure of the family business has to necessarily fit the purpose and the current environment of the business.

White collar crimes Essay Example for Free

White collar crimes Essay This paper provides a detailed understanding behind the motives of people committing crimes. Researchers have named ―the people committing crime, where the crimes were minimal and confined to a particular area of administrationâ€â€" as Grass Eaters. People involved in white collar crimes and which has spread in almost all fields of business are termed as Meat Eaters. With the advent of technology and growth of education, white collar crimes are on the rise, being protected by professionals finding loopholes in the judiciary and support from the government indirectly. This has created a nexus where people from almost all walks of life have started forming group to do white collar crimes and being protected by professionals in law. This has lead to a situation where the small timers have become white collar criminals. Talking about the prevalence of white collar crimes in India, they are spreading like a rapid fire in every sphere of society. Though corruption, one of the species of white collar crimes, has been the most talked about issue in all spheres-social, economic and political, not much stringent steps/actions have been taken to curb this menace. Therefore the concern of this paper is to define white collar crime, study its historical development and formulate tentative solutions for eradicating the problem. This thought evolved with the Criminologist and Sociologist Edwin H. Sutherland, in the year 1939, who popularised the term â€â€"white collar crimes‘ by defining such a crime as one ―committed by a person of respectability and high social status in the course of his occupation.â€â€" Sutherland also included crimes committed by corporations and other legal entities within his definition. Sutherland‘s study of white collar crime was prompted by the view that criminology had incorrectly focused on social and economic determinants of crime, such as family background and level of wealth. It is true to the common knowledge that there are certain professions which offer lucrative opportunities for criminal acts and unethical practises which is very often overlooked by the general mass of the society. There have been crooks and unethical persons in business, various other professions, who tend to become unscrupulous because of no reason apart from the thirst of gaining more and more for themselves. These deviants have least regard for ethical and moral human values. Therefore, www.indianresearchjournals.com INTRODUCTION IRJC International Journal of Social Science Interdisciplinary Research Vol.1 Issue 9, September 2012, ISSN 2277 3630 they carry on their illegal activities with impunity without the fear of loss of respect and prestige. These crimes are of the nature of â€â€"white collar crimes‘ which is the essential outcome of the development of the competent economy of the twenty-first century. CHRONOLOGICAL MILIEU OF THE EMERGENCE OF WHITE COLLAR CRIMES The earliest documented case of white-collar crime law dates back to 15th century is England. There has been a case popularly known as the Carrier‘s case of 1473, where the agent was entrusted to transport wool and he attempted to steal some of it for him. Therefore the Star Chamber and Exchequer Chamber of the English Court of Law adopted the â€â€"breaking bulk‘ doctrine as it constituted the crime of larceny. However, the growth of industrial capitalism in the eighteenth century ushered a new history of crime and criminality. The very base of industrial capitalism is based on coercion and robbery. Now, before we discuss the topic let us understand the meaning of capitalism The street crime, especially snatching and motor vehicle theft, relatively down compared to 2010, the year 2011 truly belonged to the faceless white-collar criminals. The numbers of such criminals arrested by the crime branch this year saw a massive increase — 108 per cent — as 148 people were arrested for dabbling in white-collar crime as opposed to just 71 in 2010. ―In all, around 20 organised white-collar rackets were busted last year and cash and valuables, amounting to R4.5 crore, thousands of mobile phones used in the commission of criminal activity and three dozen vehicles were recovered,â€â€" said a senior police officer. The list includes perpetrators of lottery fraud, fake recruitment racketeers, ATM fraudsters, travel agents, property dealers, agents promising fake court affidavits and death certificates as well as both men and women operating fake friendship clubs. Meanwhile, the Economic Offences Wing (EoW) of the Delhi Police arrested more than . WHITE COLLAR CRIMES IN INDIA www.indianresearchjournals.com The process of emergence of these conditioned was termed by Karl Marx as primitive accumulation‘ while in the words of Adam Smith, it was â€â€"previous accumulation.‘ Therefore, the Dutch Marxist, William Bonger contended that criminal attitude develops among the working class under capitalism due to conditions of misery and at the same time the criminal attitude develops among the bourgeoisie from the avarice fostered when capitalism strives.It succeeded in United States of America in 1890, when Congress passed the Sherman Antitrust Act which took the initiative to make the monopolistic trade illegal. Other industrialized countries like Great Britain had a history of penalties involving whitecollar crime by that time, but it was not as sweeping as the Sherman Act. Some nations implemented a smattering of these laws, known as competition or antitrust law, but did not have a strong binding force for a long time. But more anti-white-collar crime sentiment rose in the late 19th century and early 20th century in the United States as a result of a group of journalists known as muckrakers. They laid much focus on the prevalent stock fraud, insurance fraud and underhanded practices of monopolistic companies that had grabbed under the Sherman Act. The muckrakers‘ exposes gave rise to public resentment and thereby called for in some reform. By 1914, Congress attempted to solidify and strengthen the sentiment laid down by the Sherman Act, which was used against labour unions, with the Clayton Antitrust Act. This Act was much stricter and went much further than the Sherman Act in making particular monopolistic practices illegal. IRJC International Journal of Social Science Interdisciplinary Research Vol.1 Issue 9, September 2012, ISSN 2277 3630 criminals in 1,358 cases ranging from those of land grabbing to fake job rackets and attached property valued at amounts estimated to be between Rs. 350 to Rs. 500 crore. ―This year, we focused more on individual cases as opposed to those in which several persons were victimised. We got more manpower,â€â€" said Vivek Gogia, joint CP (EoW). White collar crimes are to be considered as a global phenomenon to which India is no exception. As discussed earlier, white collar crimes emerged in India with the advent of the British colonisation during the period of industrial capitalism. Prior to that, instances of men working with the District treasury embezzling with the money kept under his safe custody or bribing practiced among the officials were found. Therefore, the white collar crimes were confined to this limit. Thus, the people indulging in the white collar crimes then can to said to be mere â€â€"grass eaters‘ the people in the modern times have reached the stage of â€â€"meat-eaters‘. WHITE COLLAR -LEGAL PROFESSION WHITE COLLAR – MEDICAL In India, the white collar crimes are so wide spread that it does not confine itself in the legal arena. Similar unfortunate instances can be drawn from other professions too, like that of medical practitioners, engineers, educationalists, businessmen, politicians and the list goes on. The medical practitioners are often found involved in issuance of false certificates, carrying out illegal abortions, selling out sample drugs and medicine, even in some cases adulterated drugs and medicines to the patients. Dilatory tactics are often adopted by them in providing treatment to their patients with a menswear to extract huge amount of money, no matter the person has good practice. Some of the notorious instances are like that of Nithari 159 The instances of white collar crimes committed in the Indian society by the lawyers, there lie the shameful illustrations of Magistrates and judges involved in committing crimes. They in the name of interpreting the laws often act as the protective shield for the goons having or not-having any political colour and allow them to go free whereas they should have been subjected to deterrence. It is the most unfortunate situation at the same time devastating, because here the crimes are committed by those individuals who are being given by the State the responsibility to ensure justice. www.indianresearchjournals.com The white collar crimes became a phenomenon to be reckoned with industrial revolution. Modern industrial capitalist economy which evolved with time became complex in nature as it developed a growing commercial nexus among insurance, banking, stocks and related corporate matters. This in turn, gave rise to critical legal intricacies relating to property rights and other legal matters which paved the way for the birth of a new class of professionals of advocates who in the name of providing justice started abetting in the wrong and thereby pursued their own narrow interest. A large number of advocates evolved, who forget the pious oath of serving the society and started looking for the legal loopholes and concentrated mainly in helping out the rich entrepreneurs to grow richer. They made extensive study to try out ways for maximum tax evasion for these rich corporate personalities as well as for themselves. The white collar crimes committed by these legal practitioners only confines in sorting out illegal methods of tax-evasion. There are very frequent instances of unscrupulous and unethical practices like that of fabricating false evidence, engaging professional witnesses, thereby violating ethical standards of legal profession and dilatory tactics in collusion with the ministerial staff of the courts. IRJC International Journal of Social Science Interdisciplinary Research Vol.1 Issue 9, September 2012, ISSN 2277 3630 case, where the medical professionals put up before the society the optimum level of brutal character they can reach for the crave of making money. Misleading and fake advertisement claiming absolute cure is also one of the frequent malpractices being carried out in the medical profession. The problem lies in the fact that, they often escape punishment, since they cannot be said to have violated the letter of law, but, by violating the spirit of law, they commit crimes which are truly anti-social and creates enormous damage to the public health and safety at large. WHITE COLLAR-ENGINEERING Speaking of the engineers‘ role in having their role to play in white collar crimes, we often find instances of underhand dealing with contractors, suppliers, passing of sub-standard works and maintenance of bogus reports of the labour works. They financially earn more for their low grade works from the contractors, than they can earn for the genuine work. Therefore, many of them, out of the greed of earning more and more, play dangerously with thousands of lives of the individuals. WHITE COLLAR-EDUCATION The matter comes to the white collar crimes educational institutions do come in the league to operate with impunity. A nastier role is played by the private institutions that are least bothered in providing the education, but only concentrate of making business at the cost of the children‘s future. Even rackets operate in these institutions for procuring students to appear in the examinations on the basis of manipulated eligibility certificates, thereby damaging the standard of education in India. When it comes to the Governmental institutions, the teachers and staffs of the institutions are often found to be involved in unscrupulous practices, since they can hardly make fortune from the inadequate salary they receive from the government. Teachers often drag the students for taking private tuitions and even go to the extent of blackmailing them of ruining their future, if they deny doing so. These are only a handful of instances of white collar crimes practiced in day to day life by certain professionals in the course of their profession. The major role in committing white collar crimes are played by the business tycoons and politicians, whose greed and wants multiply with the more they acquire. In India, whenever any major scandal comes to the media focus, a through investigation always finds an unlawful involvement of political parties in it. So far as the businessmen are concerned, their acts of white collar crimes go beyond count. They are termed as the corporate criminals who more often than not,are involved in illegal contracts, combination and conspiracies of trade restraints, unfair labour practices, selling of adulterated foods and drugs, bribing of public officials so on and so forth. They take advantage of the corporate veil and indulged in a number of crimes. The recent Satyam scam case is one of the worth-mentioning illustrations, where it was seen how an individual, hiding himself in the veil of incorporation, indulge in defrauding crores of money. WHITE COLLAR- UNIVERSAL www.indianresearchjournals.com WHITE COLLAR-CORPORATE 160 The white collar crimes are often master minded and are carried out in a planned manner by technocrats in the form of scams, frauds, etc. facilitated by technological advancements. In IRJC International Journal of Social Science Interdisciplinary Research Vol.1 Issue 9, September 2012, ISSN 2277 3630 these types of offences not only the individual is being with pecuniary loss but also, such offences like peddling drugs and narcotic substances, counterfeiting of currency, financial scams are some of the crimes which evoke serious concern and impact to the national security and governance. Violation of foreign exchange regulations and import and export laws are frequently resorted to for the sake of huge profits. WHITE COLLAR- SOCIETY The major white collar crime very common among the individuals, no matter he/she belongs to the middle or upper strata of the society is that of evading taxes. The complexity of the taxation laws provided a number of loopholes through which many individuals tried to escape. A tax-evasion has known no professional or class boundary in our country. Be it an engineer, doctor, advocate, a business tycoon or a simple small industry trader-all have learnt the trick of evading taxes. The main difficulty posed before the Income Tax Department is to acquire true information of the real and exact income of these professionals. It is often alleged that only an insignificant amount of their total income is posed a income before the Income Tax Department and the rest therefore goes into the circulation as black money. The frequent modifications in the tax-laws of the country has been able to add very little to put a check on this continuing menace which is throwing a great negative impact in the Governmental revenue and thereby the growth of the country. INDIA CRIME AND FRAUD IN WHITE COLLAR 2010-2011 Annual Global Fraud Survey report of Kroll conducted by Economist Intelligence Unit gives expected results. Fraud continues to be a big problem worldwide and more so in India. Of the companies surveyed, globally 75% reported experiencing fraud during the year. Though the figure has reduced in comparison to previous year‘s 88%, the situation is still dismal. The chart below compares the top six fraud categories at global level with India. In most of the cases, India is doing much worse than its global counterparts are. Worldwide management conflict of interest, internal financial fraud, corruption and bribery and vendor procurement related frauds have increased. Physical theft of assets and information theft decreased. Indian business crucial pain points are corruption and bribery, information theft, internal financial fraud, financial mismanagement and vendor procurement. www.indianresearchjournals.com In India, the situation is disastrous, with 84% organizations reporting that they suffered from fraud during the year. It is wake-up call for India, as it is ranked second worldwide after Africa and shares the position with China. The report answers the most relevant question relating to fraud – what is the loss caused by fraud? The estimated figure given in the report is that globally organizations suffered 2.1% revenue loss due to fraud. For India, the percentage is higher at 2.4%. Further analysis available in the report says that 18% of the companies reported an earnings loss of more than 4%. A quarter of these most affected companies suffered losses more than 10%. These companies are reporting corruption, bribery, money laundering and regulatory breaches frequently. However, they are doing nothing about it. The lack of fraud prevention and investigation measures is causing huge losses in these companies. Indian companies are ill prepared to the fight fraud menace. Just 50% companies have background screening, third-party due diligence and other fraud prevention measures in place. In my view, India does not have adequately trained fraud investigators as part of the risk management teams. Overall, the focus is on financial statements audits and internal audits. These audits are not done to detect frauds. Management finds it hard to accept this fact that internal employees and related parties conduct most frauds. The report mentions that insiders conducted 60% of the frauds globally. That is, 28% junior employees, 21% senior employees and 11% third-party agents conducted frauds. In India, 59% of the frauds were conducted by internal sources. The frauds conducted by senior employees cause more damage to the company. Not only are the financial figures larger, the reputation damage is huge. However, the companies in India still do not have adequate focus on internal controls and management controls. However, government has initiated some steps to address the high level of frauds in Indian private sector. In my view, the Indian government‘s decision to give more power to the Serious Fraud Investigation Office (SFIO) in the new Companies Bill is a step in the right direction. SFIO will be in a position to conduct more investigations, arrests, raids and seizures. This would put some brakes on the escalating financial fraud cases in India. Therefore, Indian government must improve governance and take strict action against the offenders. Comptroller Auditor General is showing the way forward, the need of the hour is for political parties to have the spirit to clean up the mess. The private sector must implement fraud prevention measures and focus on ethics to reduce frauds. Both sectors have to collaborate to minimize fraud risks in India. The reasons of justifications are there for the methods used for the control of white collar crimes, the ambivalence of the social response to this sort is so related to wider social factors which have both objective and subjective dimensions. As has been so mentioned a more subjective source of ambivalence in the social response to white collar crimes is the assumption that there is less public concern about these behaviours so termed as white collar crimes, and therefore there is a less support for severe sanctions than in the cases of crimes which are traditional street crimes. But even if there was greater public ambivalence towards white collar crimes in comparison to the traditional crimes, writers such as Box has regarded this as a further challenge â€â€"to sensitize people to not seeing processes in which they are victimised disasters or accidents.‘ Therefore, the motto should always be prevention is better than cure. Since the acts involved defrauding public faith and belief, public as a whole mass should come forward to protect the whole society from these greedy people who are destroying the ethics and morality of the society slowly and slowly for their sole aim of pursuing narrow self 2. †¢ Williams Frank.

Losses In Xlpe Insulated Cables Engineering Essay

Losses In Xlpe Insulated Cables Engineering Essay Power cables, mainly underground power cables form a bulk part of electrical power systems network. Accordingly, when medium voltage XLPE cables were first installed in the late 1960s, cable manufacturers and electric utilities expected them to perform reliably for 20 to 30 years. However, history has shown that these cables had high percentage of life losses whereby the service life of some of these cables was far shorter than expected. Many cables failed after only 10 to 15 years in service. The failure of XLPE cables was happened due to the aging process. Aging of XLPE cables is related to the temperature of the insulation. For XLPE cables, the normal maximum operating temperature is 90  °C. At this maximum value, the consumption rate of anti-oxidant has been calculated to afford a cable life of 30 years. Increasing the XLPE cables operating temperature will increase the rate which the anti-oxidant is used up. Subsequently, it will reduce the service life of XLPE cables. The rea ction follows the Arrhenius relationship which is an exponential function. From this, even a small increase in temperature, it will hence give significant impact on the aging process of XLPE cables. Once the anti-oxidant in the cables is used up, the cables will start to oxidize and become easily broken. Then, the cables will be subject to stress cracking and electrical failure at positions of mechanical stress. In addition, the presence of harmonics in power system causes a conductor to overheat. This overheating process makes the cable to increase in term of temperature to its insulation. Therefore, cable will soften and the mechanical performances will reduce which is called as premature aging. Thus, it is important to investigate the presence of harmonic in any electrical equipment. From this we could know the temperature due to the overheating process and evaluate the life losses of any associated cables.

This has led to the existence of distribution-transmission line system carrying current, even if at different voltages and transporting it over long distances till the end users or customers. For the distribution-transmission line system, engineers had thought critically in finding the suitable power cables for power system. Mainly, most of the bulk electrical energy generated from the generation centers is being transported to major load centers within a large geographical area by the transmission systems using overhead lines [1]. In the other words, the distribution system delivers the electrical energy from these load centers to customers who are within a smaller geographical area. For safety, reliability and aesthetics, the electric circuits used to transport energy to such customers are usually underground power cables, though this kind of arrangement is expensive but has more advantages than the overhead lines [2]. Over the years, high demand of reliable electricity power supply has led the electricity markets to be highly competitive. Electric utility companies now have to develop means of maintaining, enhance the safety and reliability of their expensive power system components to operate advantageously and meet the demands of their customers. One of power system component that constitutes a bulk part of the distribution and transmission line systems in urban areas is the underground power cable. For instance, in the United Kingdom there are about 93000 km of 11 kV cable and more than 13000 km of 33 kV [6]. In Malaysia with rush of development has led to increasing demands of electrical energy. Doing this, underground cable distribution is increasing significantly. It is estimated that there are about 180000 km of underground cables in Malaysia, forming about 80 % of the underground power distribution system. This shows that, the technology of underground power cables has grown up very fast by the time as the world is moving extremely in science and technology. However, lately the presence of harmonic in electrical energy systems is well known [3]. The harmonics are due to nonlinear loads such as static converter and can damage the system components [6]. In the case of the cables, harmonics can cause relevant additional losses in the conducting and in the insulating materials which cannot be neglected. From the economical point of view, the presence of harmonics can cause economical damage which increasing the operating costs and decreasing the useful life of the system components. The economical damage due to harmonic losses can be defined as the summation of the operating costs and the aging costs. As stated in [13], the operating costs are referred to the costs of the incremental energy losses caused by the harmonic flow in the component, where the term incremental means that these losses are superimposed to the ones at the fundamental while the aging costs are referred to the incremental investment costs caused by the premature aging of the components caused by the harmonic pollution. Premature Aging due to Harmonic Aging failures have become a major and urgent concern in many utilities since many power system components are approaching the turning point to the end of life. For the case of power cables, the premature aging occurs due to harmonic pollution. The harmonic flow can lead to additional heating in power cables. Subsequently, temperature will rise and premature aging may result. Development of Power Cables [1] Power cable technology had its beginnings in the 1880s when the need for power distribution cables became pressing. With urban growth, it became increasingly necessary to replace some of the overhead lines for power transmission and distribution system with underground cables. The illumination of the larger cities proceeded at such a rapid pace that under some circumstances it was impossible to accommodate the number and size of feeders required for distribution, using the overhead line system approach. In fact this situation deteriorated so notably in New York City that, in addition to the technical and aesthetic considerations, the overhead line system began to pose a safety hazard to the line workers themselves, the firemen, and the public. As a result, the city passed an ordinance law in 1884 requires removing the overhead line structures and replacing them with underground power cables. Similar laws and public pressure were applied in other cities, with the consequence that by the early 1900s, underground electrification via insulated cables was on its way to becoming a well-established practice [14]. A practical lead press was invented in 1879 and subsequently employed to manufacture 2kV cables for Vienna in 1885. During the same period, vulcanized rubber was used to produce cables on a commercial scale, although use of guttapercha had already been made as early as 1846. Impregnated-paper power cables were first put on the market in 1894 by Callender Cables of England, using impregnant mixtures of rosin oil, rosin and castor oil and only in 1918 were these replaced by mineral oils. In North America, impregnated-paper cables were first supplied by the Norwich Wire Company. Varnished cambric cables were introduced by the General Electric Company in 1902. The behavior of these cables with hightemperature was subsequently improved the addition of black asphalt. Some of the more common early solid and liquid insulating employed in various underground cable installations were natural rubber, gutta-percha, oil and wax, rosin and asphalt, jute, hemp, and cotton. In 1890, Ferranti developed the first oil-impregnated-paper power cable. By following their manufacture, his cables were installed in London in 1891 for 10 kV operations. In addition, the cables were made in 20 ft lengths as the total circuit was 30 miles in length about splicing joints were four required. Nevertheless, these cables performed so well that the last cable length was removed from service only in 1933. Cable installation continued to proceed at a rapid pace, so that by the turn of the 20th century many major cities throughout the world had many miles of underground power cables. For example, already by the end of 1909, the Commonwealth Edison Company in Chicago had 400 miles of underground cable operated in the voltage range between 9 to 20 kV. Montreal had some 4500 ft cir cuits of three-conductor cables installed in ducts under the Lachine canal for 25 kV operations; the same voltage was used for cable traversing the St. Lawrence River in 1906. With some experiences behind them, cable manufacturers were increasingly gaining confidence and during the St. Louis Exposition in 1904 power cables developed for voltages as high as 50 kV were put on display [14]. Oil-Impregnated Paper Power Cables [14] During the period prior to World War I, extensive use was made of oilimpregnated paper cables of the three-conductor belted type for voltages up to 25 kV. Due to non-uniform stress distribution in the cable construction, the belted cable proved to be highly partial discharge susceptible when attempts were made to extend the operating voltage range with larger wall thickness to approximately 35 kV, to meet the increased power demand following World War I [18]. This problem was resolved by shielding the individual conductors, using 3-mil-thick copper tapes. The outside of the shielded conductors was thus maintained at the same ground potential. Figure 1.3.1 Cross-section of an Oil-impregnated Paper Insulated Cable In addition, the belt insulation was replaced with a binder consisting of fabric tapes and strands of interwoven copper wire. The purpose of the latter was again to maintain the shields of the three cables at the same potential. Over the years, the conductor shapes of the three-conductor shielded paper insulated cables have evolved into three forms, namely circular, oval, and sectoral. In many utilities a substantial portion of the present-day distribution load is still carried at 35 kV via three-phase oil-impregnated paper belted cables, with the three conductors individually grounded. There is little inducement to replace these cables with solid extruded dielectric cables, whose outer diameter for an equivalent power rating would exceed that of the ducts accommodating the more compact threephase oil-paper belted cables. Moreover, the oil-paper belted cables have been characterized by remarkably long in-service lifetimes that often exceed 65 years. Belted cables with unshielded conductors are still deployed but only for working voltages equal to or less than 15 kV. With the individual conductors shielded, it was possible to extend the use of the three-phase belted cables for voltages as high as 69 kV, though on the average their application has been confined to voltages below 35 kV. The main reason for this upper limit has again been associated with the occurrence of partial discharges, which had in numerous instances led to the deterioration and failure of the dielectric at the elevated voltages. The partial discharges were found to take place in voids, which were formed either during the manufacturing process or during the load cycling while in service. Solid-Dielectric-Extruded Power Cables [1, 14] With the discovery of the hydrocarbon thermoplastic polyethylene (PE) in England in 1933, polyethylene became rapidly, the insulant of choice for RF coaxial cables. PE was first used as an insulant for power cables in the 1950s. In the mid 1960s, conventional PE became the material of choice for the rapidly expanding URD systems in the United States. It was known to be superior to butyl rubber for moisture resistance, and could be readily extruded. It was used with tape shields, which achieved their semi-conducting properties because of carbon black. By 1968, virtually all of the URD installations consisted of polyethylene-insulated medium voltage cables. The polyethylene was referred to as HMWPE; this simply meant that the insulation used had a very high average molecular weight. The higher the molecular weight, the better the electrical properties. The highest molecular weight PE that could be readily extruded was adopted. Jacketed construction was seldom employed at that time. Extruded thermoplastic shields were introduced between 1965 and 1975 leading both to easier processing and better reliability of the cable [19]. XLPE was first patented in 1959 for a filled compound and in 1963 for unfilled by Dr. Frank Precopio. It was not widely used because of the tremendous pressure to keep the cost of URD down near the cost of an overhead system. This higher cost was caused by the need for additives (cross linking agents) and the cost of manufacturing based on the need for massive, continuous vulcanizing (CV) tubes. EPR was introduced at about the same time. The significantly higher initial cost of these cables slowed their acceptance for utility purposes until the 1980s. The superior operating and allowable emergency temperatures of XLPE and EPR made them the choice for feeder cables in commercial and industrial applications. These materials do not melt and flow like HMWPE. The emergence of power distribution cables insulated with PE have replaced a significant portion of the oil-impregnated-paper insulated power cables used at operating voltages up to 35 kV. But lower voltage PILC cables are still being manufactured, due to their in-service longevity and reliability. In spite the long record of service and reliability of PILC cables, they are being gradually replaced by the less hygroscopic polymeric insulated cables, XLPE. XLPE cables have distinct advantages which are lighter weight, better electrical and thermal properties, less maintenance, and easier terminating and jointing procedure etc. Today, XLPE cables are being extensively used in many countries all over the world. In 1959, Japan and USA commercialized XLPE cables up to medium voltage rating. Since then a fast development of XLPE cables has taken place. Presently, XLPE cable of 500 kV class has been installed in Japan. The introduction of XLPE has increased the capability of polymeric insulated cables because of their higher temperature ratings. XLPE insulations perform well at elevated temperatures. Their normal operating temperature is about 90  °C and designed to withstand an emergency overload and short circuit ratings of 130  °C and 250  °C, respectively. Technology of XLPE Cables XLPE has become the most favored insulant. Germany, USA, Asian and Scandinavian countries have installed gigantic quantities of such cables. Japan has developed XLPE cables up to 500 kV which is the highest voltage rating of XLPE cables manufactured so far. The basic material for XLPE cable is polyethylene (PE). PE has very good electrical properties. However, its mechanical strength decreases significantly above 75  °C restricting its continuous operating temperature to 70  °C only. The improved thermal characteristics of PE are obtained by establishing a large number of cross-links between its liner molecular chains employing suitable techniques. The introduction of XLPE has increased the capability of polymeric insulated cables because of their higher temperature ratings. The processes for converting PE to XLPE are electron irradiation, chemical cross linking, and organic silane method. Electron irradiation is a slow process and it is difficult to ensure an even degree of cross linking throughout the thick insulation required for power cables. Therefore this process is usually restricted to thin insulation of 1 to 2 mm thickness only. Chemical cross linking process is the process by which cross-linking of PE is established using organic peroxide such as dicumyl peroxide (DCP) at high temperature in the range 250 to 350  °C and pressure 15-20 kg/cm2. This method is employed in the production of XLPE cables of all voltage range, from LV to EHV. Sioplas technique is a relatively new method of cross linking PE into XLPE. Cross linking is achieved by mixing suitable silane to PE and exposing this to ambient conditions. This method has the distinct advantage of lower capital expenditure as no special arrangements to maintain high pressure and temperature are required. But the process is very slow for thick insulation and hence restricted to low voltage and medium voltag e XLPE cables. The general construction of XLPE cable consists of copper or aluminium conductor, extruded layer of semi conducting material over conductor (for voltage class above 3.3 kV), extruded XLPE insulation, extruded layer of semi-conducting material (for cables of voltage rating above 3.3 kV), copper wire or tape as metallic screen, armour, inner sheath and outer sheath, usually made of PVC etc. Three core XLPE cables are generally used up to maximum 33 kV. Cables of 66 kV and above voltage rating are of single core construction. Figure 1.3.2 Solid dielectric extruded power cable [14] The manufacturing process of XLPE cables consists of mixing of PE with cross-linking agent (DCP) and antioxidants, extrusion of semiconducting layers and insulation over the conductor, crosslinking the PE compound in curing lines at high temperature and pressure and cooling the core to ambient temperature. All these processes are carried out in one step employing catenaries lines for curing and cooling, hence the name continuous catenaries vulcanization. Semiconducting layers and insulation are extruded using triple extrusion technique. The curing process was initially carried out with steam at high temperature and pressure. This resulted in the formation of microvoids within the insulation and restricted the application of steam curing process up to 33 kV. To achieve reliable HV cables, it was therefore necessary to employ curing in the absence of steam. For this reason, dry curing methods were developed, where PE was crosslinked under nitrogen pressure in silicone oil, in molten salt and also in long dies. The numbers of microvoids were drastically reduced. A new curing process has recently appeared namely silane process which is more economical. Losses in Power Cables Losses in power cables include losses in conductor, insulation, sheath, and screens armors. Conductor losses (I2Rac losses) depend upon the rms current I effective AC resistance of the cable conductor. Dielectric losses comprise of losses due to leakage through the cable insulation and caused by dielectric polarization under AC stresses. It includes the net dielectric losses depend upon cable voltage, its frequency as well as the permittivity and loss tangent of the cable dielectric material, as shown by the equation below: Power loss = à Ã¢â‚¬ °CoV2ÃŽÂ µr tan ÃŽÂ ´ [2] (1) Generally, tan ÃŽÂ ´, which partially controls the dielectric losses, is significantly higher for oil-paper insulation as compared to XLPE insulation. For most of the dielectric materials used in cables, tan ÃŽÂ ´ depends upon temperature, applied stress and supply frequency. For oil-paper insulation tan ÃŽÂ ´ is also strongly influenced by moisture content. Therefore, in voltage cables, a moisture level of less than 0.05 % is desirable in order keep dielectric losses within acceptable limits. The presence of voids and microcracks can also influence dielectric losses. These voids are formed in the insulation or at the screens/insulation interfaces during manufacture, installation or operation. In polymeric cables, they are formed during the extrusion process while in paper-insulated cables, during the impregnation cycle. Voids may also form in cables by the differential expansion contraction of cable materials due to cyclic loading or short circuit conditions. These voids have a higher electric stress as compared to the bulk insulation. However, the gas inside a void usually has lower breakdown strength as compared to the main insulation. When the electric stress in void exceeds the breakdown strength of gas within the void, PD occurs. Any partial discharge in such voids increases the effective tan ÃŽÂ ´ value for insulation. Consequently, when the applied voltage is raised above the charge inception threshold, the dielectric losses exhibit a distinct increase. Similarly, impurities in the cable insulation and screening materials also increase dielectric losses. The AC current flowing along each cable conductor induces emf the metallic sheaths of the cable. Without grounding, such sheaths would operate at a potential above the ground potential and can pose a hazard. Furthermore, it will accelerate degradation of the jacket and materials, thereby affecting the cables life and reliability. When the sheaths are bonded, circulating current flows in them causing power losses. However, for three-core cables such losses are negligible. In addition to circulating currents, eddy currents are also induced in sheaths of both single and multi-core cables causing additional losses which usually are of small magnitudes. 1.5 Objectives of Study This project is conducted to evaluate the expected value of aging cost due to harmonic losses in XLPE cables. Therefore, this project is conducted regarding to these objectives: To investigate the effects of harmonics losses on XLPE cables from economical point of view. To evaluate the expected value of the aging cost due to harmonics losses in XLPE insulated cables. 1.6 Scope of study This study will focus on XLPE insulated cables This study will use the characteristics of single core underground cables. The effect of harmonics losses on XLPE cable will be investigated A program will be developed to evaluate the expected value of aging cost due to harmonic losses. The economical damage due to harmonic losses is quantified by means of the expected values of the operating costs and of the aging costs. For this, it will focus only for the calculation of the expected values of the aging costs. CHAPTER 2 LITERATURE REVIEW 2.1 Introduction We design power systems to function at the fundamental frequency [1]. In Malaysia, the fundamental frequency is standardized at 50 Hz. This design is prone to unsatisfactory operation. At the same time, failure will happen when subjected to voltages and currents those contain substantial harmonic frequency elements. Frequently, the electrical equipment may seem operate normally. However, when they operate under a certain combination of conditions it might enhance the impact of harmonics which cause results to damage [20]. Most people do not realize that harmonics have been around for a long time. Since the first AC generator began to operate more than 100 years ago (Sankaran, C., 1995), electrical power systems have experienced harmonics. When harmonics present in electrical equipment, it can cause the equipment to malfunction and fail to work. In this case proper design and rating are needed to prevent the presence of harmonics. 2.2 Power System Harmonics The objective of the electric utility is to deliver sinusoidal voltage at fairly constant magnitude throughout their system. In fact, in order to achieve this objective is reasonably complicated because there are loads that exist on the power system that will produce harmonic currents. These currents produced may result in distorted voltages and currents that can give negative impact to the system performance in different ways. As the number of harmonic producing loads has increased over the years, it has become increasingly necessary to address their influence when making any addition or changes to an installation. We should consider two important concepts that have to bear in mind with regard to power system harmonics. The first concept is the nature of harmonic current producing loads (non linear loads) and the second concept is the way in which harmonic currents flow and how the resulting harmonic voltages develop. Ideally, voltage and current waveforms are perfect sinusoids. However, because of the increased popularity of electronic and other non-linear loads, these waveforms quite often become distorted. This deviation from a perfect sine wave can be represented by harmonics sinusoidal components having a frequency that is an integral multiple of the fundamental frequency. Thus, a pure voltage or current sine wave has no distortion and no harmonics, and a non-sinusoidal wave has distortion and harmonics. To quantify the distortion, the term total harmonic distortion (THD) is used. The term expresses the distortion as a percentage of the fundamental (pure sine) of voltage and current waveforms. In addition, current harmonics can distort the voltage waveform and cause voltage harmonics. Voltage distortion affects not only sensitive electronic loads but also electric motors and capacitor banks. 2.2.1 Definition of Harmonic Harmonics are defined as current and voltages at frequencies that are integer multiples of the fundamental power frequency [4]. For example, if the fundamental frequency is 50 Hz, then the second harmonic is 100 Hz, the third is 150 Hz, and etc [5]. The presence of harmonics in electrical energy systems is well recognized due to nonlinear loads such as static converters and it can damage the system components [6]. These nonlinear loads will draw current in abrupt pulses rather than in a smooth sinusoidal manner. Then, these pulses cause distorted current wave shapes which in turn and cause harmonic currents to flow back into other parts of the power system. In the case of power cables, harmonics can cause relevant additional losses in the conducting and in the insulating materials which cannot be neglected in the cable size [6]. 2.2.2 Source of harmonics Most harmonics originate from the generation of harmonic current caused by nonlinear load signatures [4]. The major sources of power system harmonics include switching operations, power electronic devices and other nonlinear loads and etc [7]. Electronic devices are nonlinear and thus they create distorted currents even when supplied with a purely sinusoidal voltage. As nonlinear currents flow through a facilitys electrical system and the distribution-transmission lines, additional voltage distortions are produced due to the impedance associated with the electrical network. Thus, as electrical power is generated, distributed, and utilized, voltage and current waveform distortions are produced [8]. As the number and ratings of power electronic devices connected to the power systems increase, the harmonic currents injected into power system and the resulting voltage distortions have become a major problem for power quality. This is the current issues that always be taken into account nowadays. Furthermore, the installation of power factor improving capacitors may lead to resonance conditions that amplify specific harmonic currents flowing into transformers and generators. On the other hand, large industrial ac motors may also provide a path for the harmonic currents. These currents can cause overheating problems for the motors, generators, and transformers. Power grid connected electric devices which can generate harmonic currents in the power system include fluorescent light ballast transformers, induction motors, incandescent light dimmers, overexcited transformers, arc welding equipment, AC/DC rotary converters, battery chargers, computers, and any type of device that utilize s rectified AC power to drive DC equipment [9]. 2.2.3 The Harm of Harmonics Harmonics only mean trouble if the power system is not well designed to handle them. High harmonic neutral currents are a problem only if the neutral is not properly sized. Current harmonics are not a problem to a transformer if it is derated appropriately. Even some voltage distortion below 8 % THD at the point of utilization is acceptable as long as sensitive equipment is not affected. However, it is always important to be aware of the presence of harmonics and to try to minimize them by purchasing low distortion electronic ballasts and reactors for PWM ASDs. This will not only keep the harmonics in check and improve the power factor in the facility, but will also save energy by reducing losses on power system components. In addition, any time there is a considerable increase of non-linear loads, it is important to check power system components to prevent problems. 2.2.4 Effects of Harmonics on Power System Harmonic currents and voltage distortion are becoming the most severe and complex electrical challenge for th

OCR Nationals double award promoting health and well being Essay

According to the above figures given in the above Maslow’s hierarchy of needs, each aspect has been given a position in order of their importance placing the most important one at the bottom. This makes it clear that everything, (regardless the level of their importance) is important to us. There are different ways to keep up the health status up to the standard such as using medication, being on healthy diet, getting enough rest and doing appropriate exercise. After having an observational research on health and its definitions, I would conclude that to keep up appropriate health we should have healthy lifestyle in terms of physical, intellectual, emotional and social aspects. Well-being As this unit is based on promoting health and well-being, it is highly important to have concerns on well-being as well. According to the World Health Organisation, well-being explains our happiness, confidence, physical condition and general outlook of our life. It is about caring ourselves and feeling good. Well-being and living healthily go hand-in-hand. It goes beyond eating a balanced diet and taking regular exercises. It is about being aware about our life and reducing the risks of diseases. Our daily routine could decide the state of our well-being. (Bib. 4)Great Britain is a multi cultural society. The culture is a way, which is followed by a group of people. They eat, dress, behave and believe in the same way. It may be unique to that particular group. It affects their way of life and therefore their health as well. It is very important that the health care sector and the organisations respect beliefs of each culture. For example, a Christian faith group, Jehovah’s Witness urge their follower’s to refuse blood transfusions. (Bib. 12) But according to medical science, blood transfusions can save a person’s life. In another instance, Muslims don’t take pork, although animal flesh is a good source of protein. Proteins are needed for the build up of our muscles. To work properly and to be physically fit, we need to have healthy muscles. Therefore this can affect their physical health. Sometimes, the people chose to be vegetarians or vegans either following their religion or for their personal beliefs. This can lead them to be lack of proteins, as meat, eggs and other animal products are good sources of proteins. As said before, protein is very important even for making hormones. This is vital for our growth. Therefore where the PIES are concerned, it is clear that not taking animal products could also affect a person’s development. Further, this can lead our intellectual development to grow less as well because a good physical health is important to have a good memory and thinking. Another example of how different cultures consider is the fasting practise of Muslims. However, it is not good for our health to get rid of meals because it has been found that this can lead to weight loss, stomach problems including ulceration, dehydration and also changes have been observed in daily lifestyle and mental-health status. (Bib. 5) Apparently, looking at our PIES it is clear from the above disorders that this can also affect both our physical and mental health. Nevertheless, as it is linked to their culture and tradition, they don’t bother much about their health. Further, covering their body by Muslim ladies could lead to vitamin D deficiency as they are not exposed enough to sunlight causing possible rickets. On the other hand, this could be positive to avoid unnecessary exposure to sunlight avoiding risks of skin cancers. So it is clear that the cultural belief and the person’s background can affect their health positively as well. Being a Buddhist, I believe it is not right taking alcohol and drugs for a healthy life. This is another example, which shows how the background of people affects their way of thinking. As different cultures and religions consider health in different ways, it is important that doctors should be aware of cultural beliefs when treating patients. According to the beliefs and places of living of a person may cause them to have less access to medical treatments. For example, a study carried out among the people living in Southern Virginia has found out that they were lacking of medical knowledge and that they distrusted the physicians. They have claimed that most of their people were obsessed and they liked to eat much but not doing exercise. Although it wasn’t said in the study report what foods they ate, I thought that they might be eating too fatty and sugary foods, as they are some causes of obesity. Further, I got to know by reading the study, that these Virginians didn’t discuss health problems with outsiders. It is also said that this may be due to the lack of medical knowledge. I thought this might prevent them from getting suitable care. As the people distrusted the specialist, they do not take medicines prescribed by them. They think that these drugs may cause addiction. In addition, according to the participants in the study, there is a lack of American-born physicians. At the same time, the people in the area were having some concerns in meeting foreign-born physicians. This cultural difference between the patient and the provider has been identified as a barrier, which prevents the patients getting medial care. (Bib. 6) I thought this to be a good example to show the effects of cultural beliefs on people and their health. In third world countries, the people might not be in good hygienic conditions such as less purified water systems, poor housing and air pollution. This could also lead to illnesses and diseases. Some other examples of how different cultures look at their health are the Chinese treatments and the way some cultures treat patients using plants and herbs found from the forests. Although people from different cultures look at health in different ways, each person’s health is alike and will be affected in the same way. Therefore, it is important that we look at it in a positive manner.

Free Essays on Greeks

The Greeks in the 4th, 5th, and 6th centuries B.C. were creative. Unlike the societies before them the Greeks emerged as a group of people not remembered for their building designs, but rather for their creative ideas they created about life, society, and philosophy. The ideas they created would go on to spark a revolution in thinking that had never been done before in past societies. As a result from this new wave of thinking many philosophers is more important in Greek society than Homer. Homer reflected Greek ideas in his writings of the Iliad and Odyssey. The ideas in these books would go on to influence the society in which arà ªte (manliness) would become a very important virtue to the Greeks. Homers Odyssey is an epic adventure that follows the adventures of Odysseus. Odysseus is a man that encompasses all the characteristics of the ideal man in Greek society. These Greek ideals of a man include physical prowess, courage, fighting ability, personal honor, and protection of one’s family and property. Each of these virtues becomes apparent in the readings of the Odyssey. The Odyssey is also the story for the coming of age of Odysseus’s only son Telemachus. In the Odyssey Odysseus’s only son Telemachus finds himself to stand courage against the many suitor who pursue his mother, and their family riches. Chapter 2, and 3 embark young Telemachus on a journey to find the fortune of his fathers’ disappearance. In the beginning of chapter 2 young Telemachus is overwhelmed by the persistence of the suitors to marry his mother. Telemachus then proposes to the suitor that he will embark on a journey to find his fathers where about. Telemachus proposes that if his father is dead, than he will allow one of the suitors to marry his mother. However if he finds out that his father is still alive then he will wait for another year for his father to return, and if he does not he will then wed one of the suitors to his mother...
