Electrical Power Transformer | Definition and Types of Transformer
Definition of Transformer (adsbygoogle = window.adsbygoogle || []).push({}); A transformer is a static machine used for transforming power from one circuit to another without changing frequency. This is a very basic 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 ...
