wattmeter on a balanced load. Using this on an unbalanced load will lead to an inaccurate reading for power. To complete this method a reading with a wattmeter connected from a single line to neutral via the voltage probes and in line with the line on the current probes. By multiplying the value of the wattmeter by three the total system power is found. The second method of measuring three phase power is the useful for both balanced and unbalanced loads. By connecting a wattmeter with its current probes
What are the effects of power outages on businesses in South Africa? Power outages create problems in the socio-economic development of the country because businesses, factories, shops, hospitals etc. struggle to continue functioning due these outages. The elderly, sick and very young are the most vulnerable, especially during the colder months. Students are also affected, they sit in the darkness and are unable to study or work. Patients also suffer terribly because operations stop in hospitals
2.1 (c) Total Harmonics Distortion (THD) The total harmonic distortion is calculated as the ratio of the rms value of its total harmonic component of the output voltage and the rms value of the fundamental component. A total harmonics distortion is an evaluate of closeness in a shape between the output voltage waveform and its fundamental components. THD=√(E_rms^2-E_1^2 )/(E_rms^1 ) 2.1 (d) Distortion Factor (DF) A distortion factor shows the amount of harmonics that remain in the output voltage
electrical power generating system has always been an important concern in the electrical power industry. The growing size of power grids, huge demand and crisis of energy across the world, continuous rise in price of fossil fuel necessitate the optimal combination of generation level of power generating units. The problem of Economic Load Dispatch (ELD) is to minimize the total cost of power generation (including fuel consumption and operational cost) from differently located power plants while
ATTs use of Total Quality Management The following is an attempt to analyze AT&T's use of Total Quality Management throughout its organization. Since AT&T is an elaborately enormous corporation I will focus my study to AT&T Power Systems/Lucent Technologies. This division of AT&T has been the industry standard for excellence since TQM was first introduced to the company. AT&T Power Systems has become one the world's most dynamic companies because of its use of TQM. I will provide a brief description

computational procedures used in power system analysis. The load flow problem can be defined as: Given the load power consumption at all buses of a known electric power system configuration and the power generation at each generator, find the power flow in each line and transformer of the interconnecting network and the voltage magnitude and phase angle at each bus. Analysing the solution of this problem for numerous conditions helps to ensure that the power system is designed to satisfy its performance
performance and characteristics of a centrifugal pump, its motor, and the corresponding piping system, used to pump an ethylene glycol solution. The pump used in this experiment has a performance curve based on water, so pump performance curves, as well
due to the amount of deaths and destruction. Clausewitz theories of absolute war, war as a continuum of policy, and the presence of friction in war best characterized the nature of World War I. The initial onset of World War I was considered total war. Total war is a war that is unrestricted
Question #1 Power-control theory of crime combines Marxist conflict theory, social control theory and feminism and was theorized by Canadian criminologist, John Hagan. A prominent theme throughout the power-control theory is that social power in society is predominantly patriarchal, or male dominated. Deutschmann (2007) identifies five elements of the power-control theory: (1) The social class system determines the hierarchal ranking of individuals in terms of social power; (2) The class position
atomic bomb was tested in New Mexico and the next month the second and third weapons off the production line were dropped on Japan. Since then no nuclear weapons have been used in anger, although tens of thousands have been accumulated by the major powers and their destructiveness and sophistication increased immensely.” The nature of warfare is constant and evolved from multiple factors and military revolutions over time. The purpose of this paper is to identify the most important military revolution
Although the system of checks and balances and the separation of powers are essential to the establishment of the government, it makes the constitution negative and positive. In order to secure the rights of everyone, the system of checks and balances is necessary. It is not only for protection from the oppression of society’s rulers but also the injustice of one fraction of society to another. If the governed suspects that the legislative has abused its authority, such as using its powers for personal
volcanoes, geysers, and hot springs. Iceland has a total land area of 39,770 square miles with Reykjavik as their capital, and 2,796 square miles of water area. Their total population consists of about 317,593 people. (Aronson, 2010) Iceland is a constitutional republic; a state where the head of state and other officials are representatives of the people and must govern according to existing constitutional law that limits the government's power over all of its citizens. Iceland became a republic
pushing future long term manned missions to celestial bodies within our solar system into the realm of possibility. A manned mission to Mars – especially one for colonization – would certainly fall into the long term mission category and so habitation will be a central part of my explorers’ journeys. Mariner 6, our fastest
was a success compared to other European countries in this time period, it wasn’t a total success because there were still some failures although the successes do outweigh the failures. The political system in the FRG was a total success. The Basic Law, which was the constitution of the FRG and outlined the political system of the FRG was a total success because it allowed freedom of speech, it gave more powers to the lander making the FRG more federal meaning that the regions had a bigger influence
States governmental system and totalitarian regimes such as Nazi Germany with Hitler and Stalinist Soviet Union. Wolin central points are how are government is highly managed, money-saturated elections, the lobby-infested Congress, the imperial presidency, the class-biased judicial, the penal system, and the media. Inverted totalitarianism is different from traditional forms of totalitarianism. It doesn't
the damages were terrible. Chernobyl Disaster Brief Description On April26, 1986, the nuclear power plant was exploded in Chernobyl, Ukraine. At 1:23 AM, while everyone were sleeping, Reactor #4 exploded, and 40 hours later, all the city residence were forcefully moved to other cities, and they never return to their home. The Chernobyl disaster is ranked the worst nuclear accident. The Chernobyl nuclear power plant was ran by the Soviet Union central nuclear energy corporation. (International Atomic
Proportionality as the Most Important Feature of an Electoral System Many people citizen many of the electoral systems are that they try to produce a single winner therefore distorting proportionality and the distribution of preferences among the voters. These systems are designed to produce a balance between the total number of votes and the total number of seats which it receives from the legislation. Proportionality is basically about fairness but elections are not always fair, for example
science world, the usage of power is very high. As the usage is increased, the power demand is also gets increased. In order to comprise/compensate the power demand, different forms of power sources are preferred. Dispatchable energy resources (non-renewable energy sources) are the sources can be turned on and off in short amount of time and it is generated from different techniques. Non-dispatchable energy resources (renewable energy resources) includes the nuclear power plants, hydroelectric plants
Fascism and Why does it Emerge? The purpose of this essay is to explain what fascism is and why it emerges. Fascism is a political ideology that consists of an all powering totalitarian government, which has total control of the people, the nation and the economy. The fascist economic system creates an upper class for the owning/ruling class and leaves the working class in a lower state who in turn produce for the elite. To justify themselves as beneficial to the oppressed lower class, the fascist
