· B-phase transformer (EMTU-TT01) · Feedback electronic wattmeter · Multi-range moving-iron ammeter · Instrument voltage transformer THEORY AND INTRODUCTION ----------------------- Transformers are used all over the world to step-up and step-down electricity. The transformer is one of the most commonly used electrical devices. The reason the transformer is so popular is because they range in size from 240V to well over 240kV, stepping -up and stepping-down electricity all over the world.
In this time of age, things have been consuming a lot of electricity compared to the old electrical appliances. People have been innovating different types of electrical appliances to reduce the amount of electricity used by the household such as air conditioner, refrigerator, television, and other appliances. One way of saving electricity which have been introduced in the new era is the Bio Robot Refrigerator introduced by a student from Russia, Yuriy Dmitriev, which is one of the 25 finalists in the Electrolux Design Lab competition. The competition is to challenge the entrants to redesign the modern appliances for the future.
Ever since I was a child, I have had a great interest for the automotive industry. From car trivia to novel innovations, my innate passion for the automotive industry has always made me research the minutest detail of every vehicle that interested me. Since elementary school I would draw sketches of cars which incorporated technology which were unheard of at that time; novel devices such as electrochromic windshields, HUD displays, and wind turbines which would constantly re-generate electricity for the car. While growing up, my hobbies largely consisted of constructing countless Lego and Meccano sets, and repairing my mom’s 19 year-old car. In middle school, math and science were my favorite subjects: applying science and mathematics to solve real-world problems has fascinated me and I have also taken further steps to reach my goals. By the age of thirteen I devised a scaled model of a heliostat power plant, which successfully powered a light bulb. The mathematics beyond the focus points of parabolic dishes and thermodynamics was very advanced for my age, but I took up the challenge...
The electricity grid is the term for the network of power lines, transformers, and any other tool required for the transportation of electricity to the consumer’s house. The current grid relies upon the workers to collect the data needed and report back to the engineers and overseers who then instruct how to maintain the grid. Now, in the computer age, the smart grid has been made possible. The smart grid is similar in concept to a smartphone. Smartphones are run by powerful computers that provide the maximum efficiency possible to give the phone more features and run faster. This is what the smart grid can do; it maximizes grid efficiency and makes it compatible with newer technologies. The smart grid incorporates two-way comm...
For the prevantion of the electricity blackout we need to build smart power grid. A modernized electrical grid that uses analog or digital information and communications technology to gather and act on information, such as information about the behaviours of suppliers and consumers is known as a smart grid. This is used to improve the efficiency, reliability, economics, and sustainability of the production and distribution of electricity in an automated fashion[12]. The important aspects of smart grid is to electronic power conditioning and control of the production and distribution of
Energy is the basic necessity of daily life. Nowadays, dependence on fossil fuels for energy needs becoming lower in numerous countries due to the potential of renewable energy to supply sustainable energy to the huge populations in many developing countries who are short of clean and continues energy. Generally, renewable energy can be defined as energy that is derived from natural resources which are constantly replenished and theoretically inexhaustible. Fossil fuels on the other hand can be described as energy that cannot be renewed and will eventually diminish. Thus, in many developing countries renewable energy is the alternative energy to replace non-renewable energy or commonly known as fossil fuels. In addition, according to Sorensen (2004), there is a greater demand for renewable energy sources nowadays due to the uncertainty of fuel price rise in living expenses. Commonly, there are many types of renewable energy available in our world such as wind power, biomass energy, solar energy, hydroelectric power and geothermal energy. However, the main three example of renewable energy are hydroelectric power, solar and biomass energy (Refer to Figure 1 in Appendix 1).
Today our society is using more energy than ever. With the increase in demand for energy, problems are presented that have to be addressed. One of the biggest and most prevalent problems is the need for clean, renewable, sustainable energy. On the forefront of these problems comes the following solutions: nuclear energy, hydro-electric energy, and photovoltaic energy. With the need of energy in today’s current world, exploring different ways of producing power are necessary. The differences and similarities of nuclear energy and alternative energy are important to look over and examine in depth, so that it is plain to see the positive and negative effects of energy production.
...d find the right one, it gave me a sense of accomplishment and satisfaction that was indescribable. One is faced with many challenges like these as an electrical engineer, but it is worth all the trouble because once the program, device, or circuit works right, and is used by many people for different purposes, one feels accomplished and is ready to try a new challenge with a higher sense of self esteem.
I remember as a kid sitting on the lap of my father, while I was holding the wheel and he was controlling the gas pedal. I asked him questions like “How does a car start?” He would answer in simple words by saying, “This car starts when we put the ignition key; the power from the battery reaches the small gears (starter motor) and the big gear (the flywheel) will meet, causing the fly wheel to start rotating: then the car starts. “How come when we step on the gas pedal the car starts moving?” “This actually happens by the clutch of the car, which is used to smoothly transfer power from the engine to the wheels. And if it is pressed forcefully, the gas pedal causes friction with the ground, making a noise. So that is why it should be stepped on gradually.” These trips not only made me learn about technology more, it made me develop a relationship with my father. This was a big triumph for me and I continued to go there. In my freshman and sophomore year I volunteered at this place. When I was volunteering my father would give me projects to repair one of the cars with him and together we would do so. Through my time at EPEI, I realized that knowing one particular subject is not enough. I favored

In the search for alternatives to fossil fuels, scientists and policy makers have focused on three options: nuclear power, energy from biomass; and a combination of wind, water, and solar power. Nuclear power, however, is much more costly and runs the risk of having it fall into the wrong hands where it could be turned into a weapon of mass destruction. The third option entails wind turbines, photovoltaic power plants and rooftop systems, concentrated solar thermal power plants,...
