Definition of Transformer
A transformer is a static machine used for transforming power from one circuit to another without altering frequency. This is a very clear definition of transformer.
History of Transformer
The history of transformer was commenced in the year 1880. In the year 1950, 400KV electrical power transformer was introduced in high voltage electrical power system. In the early 1970s, unit rating as large as 1100MVA was produced and 800KV and even higher KV class transformers were manufactured in year of 1980. Use of Power Transformer
Generation of electrical power in low voltage level is very much cost effective. Hence electrical power is generated in low voltage level. Theoretically, this low voltage level power can be transmitted to the receiving end. But if the voltage level of a power is increased, the current of the power is reduced which causes reduction in ohmic or I2R losses in the system, reduction in cross sectional area of the conductor i.e. reduction in capital cost of the system and it also improves the voltage regulation of the system. Because of these, low level power must be stepped up for efficient electrical power transmission. This is done by step up transformer at the sending side of the power system network. As this high voltage power may not be distributed to the consumers directly, this must be stepped down to the desired level at the receiving end with the help of step down transformer. These are the uses of electrical power
The power lines you see throughout the country that is being suspended above the ground with the help of tall metal towers is designed to carry and transport high voltage transmissions. This is important because at this stage the higher the voltage the more efficient as it transports throughout the network of power lines. Once the voltage passes through transformers the voltage is lowered to a level that is suitable to being distributed for safe usage.
Early engineers realised that higher voltage results in lower current through the power lines, resulting in lower power line losses. Today, long-haul power lines run at voltages of 300,000 volts in order to minimize the power loss. “Using transformers, it is easy to boost AC voltage to these high levels and then reduce this and reverse the process at the consumer end. DC doesn’t work in a transformer.”

Electrical Engineering is “ The branch of engineering concerned with the generation, transmission, distribution, and use of electricity. Its two main branches are power engineering and electronics (including telecommunications). Electrical engineering emerged in the late 19th century with the mathematical formulation of the basic laws of electricity by James Clark Maxwell, followed by the development of such practical applications as the Bell telephone, Edison’s incandescent lamp, and the first central generating plants. Electrical power engineers design generators, power stations, and electricity supply systems as well as electric motors and transport and traction systems. Electrical engineering is an applied science involving mathematical skills and a knowledge of physics, in addition to the basic engineering subjects” (The Macmillan Encyclopedia). Electrical systems have always fascinated me since childhood, and figuring out the engineering behind everything I could get my hands on was another passion I have always had. When getting out of the military and deciding to go to college electrical engineering was the only major that really stood out to me as a way to combine both my childhood interests. My third year at college and I still stand firm with my decision as I continue to excel in my classes directed toward my major while the classes further ignite my passion for the field of study.
Air conditioners cool the surrounding air by relying on the property of gases. When the pressure of gas decreases, the gas will cool and expand. If the pressure is increased, the temperature will increase. The phase changes are known as condensation and evaporation.
The Industrial Revolution was an extremely important historical process in which the societies and cultures in the West, and then throughout the world, transformed under the influence of technological and scientific progress. The Western world, as industrialized as it is today, is the final result. Two major inventions, the steam engine and electricity, were both crucial parts of the technological progress that turned the wheels of the Industrial Revolution.
In 1891, Tesla invented the Tesla coil, a type of high-frequency transformer that is still used in radio and television transmission. He experimented with wireless control, and, in 1898, he demonstrated a radio-controlled boat he had invented. In 1899, Tesla created artificial lightning in one of his laboratories. Tesla's other achievements include early experiments with X-rays and radar, aircraft design, and the invention of neon and fluorescent lighting.

The Industrial Revolution took place from the 18th to the 19th centuries. The Industrial Revolution was a period during which predominantly agrarian, rural societies in Europe and America became industrial and urban. Prior to the Industrial Revolution which began in Britain in the late 1700s, manufacturing was often done in people’s homes, using handtools or basic machines. Industrialization marked a shift to powered, special-purpose machinery, factories and mass production. The iron and textile industries, along with the development of the steam engine, played central roles in the Industrial Revolution. The way the iron and textile industries and the development of the steam engine played central roles in the Industrial Revolution is the things they led to such as improved systems of transportation, communication and banking.
While working for Dover Chemical the largest assignment that I was given was to aid a contracting engineer with a power distribution project for the plant. Power distribution is the transfer of energy, or electricity, from one location to another. However In order to understand power transfer from generation to distribution it is important to understand the process from start to finish. AC (Alternating Current) is used for this transfer because of its ability to transmit over longer distance with lower losses by using transformers. Power is lost in transmission lines due to its resistance, the longer the transmission line the higher its resistance will be, however when using polyphase AC current we are able to change the voltage levels through the use of transformers. There are step-up transformers and step-down transformers both are used when transporting power from one location to another.
In industrial wiring electricians start dealing with high voltages such as 600 volts or higher. They wire big machines and any other component that the company needs to be successful and safe.
How is the energy source able to produce power? (How it works, are generators/motors used, how does it produce electricity etc. Include images)
We can obtain energy in a useful form by a system called Energy Harnessing Network. In this complicated system we extract raw energy in the form of heat energy, light energy, solar energy etc and then transformed it into fuel for example coal, natural gas, petroleum and electrical energy then stored it and use when needed. The engineers did a lot of work on it and successfully did what was think impossible in the earlier time. They harnessed energy in many different forms such as hydropower, solar power, wind mills and nuclear power etc.
A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors
From a producer 's point of view it is helpful to plan and incite a set scope of transformer sizes. Usually, the terminal voltages, VA rating and frequency are assigned. These specifications decide the materials to be utilized and their measurements. This way to deal with transformer outline has been used and displayed in point of interest in standard course book. It has been used as an outline execute for enlightening college classes at universities., it has been utilized widely as a part of outlining transformers for exchanged mode power supplies. Nonetheless, by outlining to evaluated details, thought is not unequivocally given to what materials and sizes are really accessible. Coreand winding material suppliers offer inventories of favored sizes, especially so for littler rating gadgets. This mirrors the supplier 's assembling abilities in expulsion, rolling and shaping devices and gear. It is not monetary to offer clients any size and shape they require. It is conceivable that a specialist, having planned a transformer, may then locate the material sizes don 't exist. The specialist may then be compelled to utilize accessible materials and hence the execution of the genuine transformer that is fabricated is prone to be essentially unique in relation to that of the outline counts. Because of troubles in assessing genuine winding measurements, the spillage reactance specifically may not be computed effectively. The leakage
