An electrical power transformer is a static device that transmits electricity from one terminal to another terminal or one circuit to another circuit without changing frequency and physical wire connection. The transformer is used to change the voltage. In 1831 transformer was first invented by Michael Faraday. The approximate longevity of a transformer is 30 years.
It works continuously with the approx of 95% efficiency. According to the range, three types of transformers are seen now time. They are small, medium, and large power transformers. Small transformers output voltage up to 7500 KV, the medium transformer is 1000KV, and the large transformer is 1200KV.
Electrical Power Transformer Definition
A power transformer is a device used to change the voltage on both sides of an AC and Load connection. Transformer increase (step-up) and decrease (step-down) voltage. The transformer converts a high current of low voltage to a low current of high voltage and also converts low voltage to high voltage as well as low voltage to high current.
Transformer safes electrical equipment by hampering to transmit extra voltage to the secondary loads. An isolation transformer is an example of it. The transformer works on the principle of mutual EMF induction.
The transformer is needed in every step of supply, starting from power generation. That’s why it is a very important electrical instrument for the power sector.
