...Electrical Power Assignment 1 Task 3 – Q4 3 Phase Transformer Construction Diagram Description As shown in the diagram above, a three phase has three sets of iron cores instead of the one of a single phase transformer. Each ‘leg’ of the transformer has its own primary and secondary windings. Each primary winding will have the same amount of coils as will each secondary winding. The three primary windings (shown above as P1, P2 and P3) and the secondary windings (shown above as S1, S2 and S3) can be connected in either a star or delta arrangement to give a required output. Also the output could be wired in a zigzag arrangement for special purposes where a phase shift of 30° is required. Core Types There are a few different types of core that are used in transformers, some are described below: Solid Cores Solid cores are just made of solid iron and are used in circuits such as switch mode power supplies which operate above mains frequencies and even up to a few kHz. The materials used in these cores combine high magnetic permeability with high electrical resistivity. Laminated Steel Cores These cores are made from layers of high permeability silicon steel and are usually used at power and audio frequencies. They are used because in a solid core at high frequencies ‘eddy currents’ are formed. The laminations confine eddy currents inside each lamination and so decrease the losses. Air Cores An air core is simply a transformer without any core at...

...The electric utility industry generates, transmits and delivers electrical power to consumers, businesses and governments. Today there are three primary business structures in the regulated electrical utility industry—public companies owned by shareholders, municipally owned companies, and those owned and operated by the federal government. Shareholder owned companies are the largest group, providing half of all electricity in the United States. Burning fossil fuels to power steam turbines produces over half of electricity consumed today.1 Other generation methods include harvesting the power of nuclear reactions to power turbines and, increasingly, renewable methods such as wind or water-powered generation. Unlike most manufactured products electricity cannot be stored, so a complex and delicate fabric of transmission systems (know as the power grid) exists to deliver power when and where it is needed. Many firms involved in the generation of power are also involved in its transmission and sale to end-users, making vertical integration commonplace within the industry. This end-to-end integration, as well as end users’ dependence on electricity, has led to historically strict government control of the industry. The most significant piece of regulation in the last century was known as the Public Utility Holding Company Act of 1935 also known as PUHCA. The act had a profound effect on the regulated electrical industry. First, and most importantly, it set limits on the rates...

...General Electric Power Company April 4, 2014 Mrs. Linda A. Smith 4312 Beautiful View Line Jacksonville, FL 32256 Dear Mrs. Smith: For more than 100 years, General Electric Power Company (GEPC) has been providing efficient, inexpensive electrical power for your community. While the cost of generating electric power has gone up raptly, GEPC’s base rates have not changed since 1975. We have avoided raising our prices for as long as possible, but we can no longer prolong the inevitable. Our board of directors has just voted to increase base rates by 33 percent over the next six months, so we can continue to provide the quality and service you’ve come to expect. However, we cannot be certain the rate increase will be enough to save the company and more rate increases are passable. To reduce the impact on our valued customers, the change will be implemented in a three-step plan over the next six months: Step I: May-Jun 2014 will increase of about $11, or 11 percent, per month, effective for a GEPC residential customer in Jacksonville using 1,000 kilowatt-hours (kWh) per month. Step II: July-September 2014 will add another $11, or 11 percent, per month, based on 1,000 kWh average bills, bringing the total increase to about $22 per month. Step III: October 2014 will result in the last monthly increase about $11, or 11 percent, for a residential customer using 1,000 kWh per month. This completes the total increase to about $33 per month. We thank you for...

...CHAPMAN Luotang Power: Variances Explained Introduction As soon as Tan Min Yi received the 2011 Report of Operations for the Luotang Power Company, he called company Controller Fiona Zhu and Sales Manager Ricky Wang into his office to discuss the results. Tan was general manager of the Luotang Power Company, a 600 Mega Watt (“MW”)1 coalfired power plant, located in Hubei Province, China. He was scheduled to make a presentation to the Board of Directors of his parent company, China Hua Tong Power (“HT Power”), the following week about the most recent results and was concerned about their reaction to the disappointing results.2 Tan knew his company had performed well during the year. Both plant availability3 and fuel economy had improved over the previous year. Additionally the plant’s primary customer, the Hubei Provincial Power Company (“HPPC”), had met its contractual electricity purchase obligations for the year. However, there had been limited opportunity to sell energy above the contractual minimum, either to HPPC or others. Still, Tan felt that these factors were outside his control. His team had performed well—it just didn’t show up in the financial results. The scheduled presentation to the Board was important for two reasons. First, HT Power was considering a 2,000 MW expansion at Luotang. However, on a more personal note for Tan, he had been general manager of Luotang since 2002, and he hoped it would be time for a promotion. He hoped that HT Power would consider him...

...Solar power as away of providing heat and electrical energy from heat The Sun the heat of the sun is about equivalent to burning a billion trillion tons of coal an hour. Even though only a small fraction of that heat ever reaches the earth it is still more then enough to power the whole world. People seemed to realize the importance of the sun around 30,000 BC. This was when people first started planting crops of wheat. They realized plants did better when planted in the sun over the shade. This caused them to worship the sun as a God. Many cultures built large and extravagant temples to worship the sun in. Other cultures built places to observe the sun in, such as Stonehenge in England. Different Types of Solar Panels There are three main types of solar panels. They are flat plate collectors, focusing collectors, and solar cells. The first kind is a flat plate collector. Flat plate collectors are fastened on the top of the roof of a house. They usually either heat the house or its water. A flat plate collector consists of a black rectangular frame, two or three sheets of glass, and copper plumbing. A flat plat collector uses the greenhouse affect. The sun rays go through the glass but can’t get out through the glass. The sun rays heat the water-filled copper tubes. Then the water is used to heat the home or water. Another type of a solar panel is a focusing collector. They consist of a mirror or mirrors...

...n one of the few in-depth treatments of power in conflict situations, Hubert M. Blalock begins by acknowledging something most of us know but rarely state: "The concept of power is both exceedingly slippery to pin down and yet indispensable in enabling one to analyze...."[1] Having defined power, as in physics, as having both potential and kinetic forms, he opts for the latter usage alone in his text. That is, he acknowledges power as both the capacity of an individual or group to accomplish something, and the actual doing of something, but he limits his discussion to "actions actually accomplished." Additional insights into understanding power are offered by Beyond Intractability project participants. This has two advantages. First, it dovetails with how most of us think about power most of the time. Second, it is easier to quantify. It is much easier to measure something that has occurred than something that is a possibility. An actual occurrence is a fact that can be checked. There may be disagreement on the sources of its occurrence, but the argument about its occurrence is likely to be short-lived if adequate facts can be brought to bear. If one side has won in a disagreement (in that it has gotten the other to do something it wanted), we have prima facie evidence that the first is more powerful -- or at least has exerted more power -- than the second. Since concerns of relative power are important in conflicts, it is helpful to have a clear picture of who has...

...this case would be whether or not Cooper should complete the purchasing even with a high financial risk and profound operational and organizational ramification. Fist let’s use Porter’s Five Forces to analyze Cooper Industry. Bargaining power of new entrants Level: Medium Cooper tried to fulfill their goals of growth and diversification through acquisitions, and they did success. The diversification allowed Cooper to do the business in many different industries. For example, Cooper began the diversification in 1967 when it acquired the Lufkin Rule Company- a hand tool business. After that, it acquired two more hand tool business companies in 1968 and 1970. Although there were competitors in all the industries that Cooper diversified into, the operation strategy makes Cooper have a stable market shares in different industries. Bargaining power of substitutes. Level: Medium Low Cooper actually had a pretty wide range of product market, which is the result of their acquisition. There will be even less substitution if Cooper focus on their business of making engines and compressors to propel natural gas through pipelines. Later, with a wider products market, Cooper can definitely decrease the power of their substitutes. Bargaining power of supplier...

...type of costs.- Implement the proper training for the managers, so that they do not make any mistakes which cancreate problems for others.- Elaborate the correct verification of the data so it does not create differences of opinions or mistakes from period to period. 4. The first issue was about how to evaluate managers’ performances in situations where the numbers were distorted by uncontrollable factors. So Rob Cushman could try to dothe following:- Call some energy companies and ask them to diagnose the transformer problem further and figureout if there any other ways to fix the problem permanently.- Have some back up electrical units, such as generators, just in case the power failure continues toexist.- See if there is a pattern in the power failures. If there is, try to set a schedule around the power cutand work as fast an efficient as possible while power is still available.The second was an issue as to whether to increase the proportion of total compensationthat was linked to individual performance evaluations. And Rob Cushman could figurethis out by doing the following:- Create a report based system where managers can use a check list and/or a critique worksheet andwrite down what tasks their team has completed for the day or week. As the managers check off theduties, they can determine the total compensation based on:o If the employees on that team were productive and met their...

...overkill to that’s insane?? Answer: - Thermostats protected by locked boxes, will set at 80* in the summer and 70* in winter. It represents these temperatures are the allowed ranges, not the actual set points. We usually set the temperature between 76 and 80 during the summer and between 66 and 68 in the winter when in heating mode. So, I would have opinion that employees would have find it ‘’OVERKILL’’. Few suggestions that would make a company to energy oriented usage. a. Keep the air conditioner not cooler then 78* and the heater not warmer than the 68*, set the AC temp higher or the heat temp. Lower when you are away, or turn it off completely if no required. b. Microwaves, personal refrigerators, and fans will be banned if any electrical cord found to be cut, THATS SEEMS TO BE INSANE. As it cannot be considered as the fault of all employees, it make occur by default as well. c. Use the ceiling fans found in all the rooms to stay cooler and to help AC do its job. As well as computers turned off after 7pm would make me feel THATS FINE, as it helps to save energy. d. Recycling barrels availability throughout the building seems to be impressive idea. So employees will consider it THATS FINE Q2. Then think about any actions that you and the local managers may be able to take that will offset some of the resistance of employees. For example, can you change the dress code seasonally to make the office environment more comfortable? What changes can employees themselves...

...Homework 1 Directions: Read the paragraph below. It comes from a real situation encountered in one of the Big Three U.S. automobile manufacturers. Diagnose the errors that might have been made in managing across the various functional areas that were involved in designing the automobile. The total amount of electrical power in a vehicle is determined by the capacity of the alternator. The power must serve over twenty subsystems, such as the stereo, the engine, the instrument panel, and so on. These subsystems are developed and controlled by separate “chimney” organizations, and power allocations must be made for each subsystem. The problem was, in this vehicle program, when the requirements of all the chimneys and teams were added up, they equaled 125 percent of the capacity of the alternator. Keith, who had recently taken over as head of this vehicle program (which had made changes in direction and was behind schedule to begin with), called a meeting of the Program Steering Committee designed to resolve this conflict and reach a compromise. However, many of the chimney representatives who were members of the team came to this meeting with instructions from their bosses [who, incidentally, did their performance appraisals] not to make any compromises, but to make certain that their chimney “got what it needed” and “didn’t lose out.” After Keith presented the group with the problem and the need to reach a compromise solution, their response surprised him: “It’s not our problem...

...“Electrical Engineer” My field of study is Electrical Engineer. New technology in my field: The field first became an identifiable occupation in the late nineteenth century with the commercialization of the electric telegraph and electrical power supply. Definition of electrical engineering. : A branch of engineering that deals with the practical application of electricity especially as related to communications, the distribution of power, and the design and operation of machinery and equipment. Early experiments with electricity included primitive batteries and static charges. However, the actual design, construction and manufacturing of useful devices and systems began with the implementation of Michael Faraday's Law of Induction, which essentially states that the voltage in a circuit is proportional to the rate of change in the magnetic field through the circuit. This law applies to the basic principles of the electric generator, the electric motor and the transformer. The advent of the modern age is marked by the introduction of electricity to homes, businesses and industry, all of which were made possible by electrical engineers. Some of the most prominent pioneers in electrical engineering include Thomas Edison (electric light bulb), George Westinghouse (alternating current), Nikola Tesla (induction motor), Guglielmo Marconi (radio) and Philo T. Farnsworth (television). These innovators turned ideas and concepts about electricity into practical devices and systems...

...Introduction An emergency is defined as: An emergency is a situation which poses an immediate risk to health, life, property or the environment. Most emergencies require immediate intervention to prevent worsening of the situation, although in some situations reducing the impact of the incident may not be possible and the assistance available to you may only be able to offer care during the aftermath. The key things to be aware of when and emergency occurs are: Prior planning will help you take charge of the situation. Any plans you have prepared will change during the emergency……be flexible. Prime responsibility is the safety of people. You need to act appropriately, decisively and quickly. To help an emergency run as smoothly as possible it is vital you plan for all possible scenarios in advance: Each emergency is unique and by definition will be unexpected but if you have done some preparation in advance you can increase the chance of things going smoothly when the unexpected happens. Some of the procedures to manage and emergency are generic, and where this is the case they have been included in this manual. Dealing with a serious injury Before you intervene ask yourself the following questions? Is the first aid box clearly located and full with kit. Have you gotten the correct number of first aiders present? Allow the first aiders to take over the responsibility. Is the emergency document procedure up to date? Does everyone present...

I will refrain from any form of academic dishonesty or deception, such as cheating or plagiarism. I am aware that as a member of an academic community it is my responsibility to turn in all suspected violators of the honor code. I understand that any failure on my part to support the Honor System will be turned over to a Judicial Review Board for determination. I will report to a Judicial Review Board hearing if summoned. Signature: Gary Martin- 1/17/2016 Narrative My Topic for this research paper is Troubleshooting Electrical Circuits. I have a little experience with troubleshooting and maintenance of electrical circuits. I used to work in maintenance for a gentleman that owned twelve Burger Kings in my area. It was a very busy job, especially with regards to electrical issues. These Burger Kings had a lot of equipment, signs and electronics that required electrical power. Most of the equipment required extreme heat and for extended periods of time. When I started the job, I would go into one of my BK’s and the first thing I would do with an electrical issue was to test the issue to see what results I might get, most of the time the equipment just didn’t work at all. I would then go turn off the power to the equipment but, first I would make sure the breaker wasn’t thrown and the equipment had been properly plugged in to the power outlet to...
