what is transformer and protection of transformer

Question

Accepted Answer

A transformer is an electrical device that transfers electrical energy from one circuit to another through electromagnetic induction. Protection of transformer involves measures to prevent damage to the transformer due to various factors.

Transformers are used to step up or step down voltage levels in power transmission and distribution systems.
They consist of two coils, primary and secondary, wound around a common magnetic core.
Protection of transformer involves measures such as overcurrent protection, overvoltage protection, and differential protection.
Overcurrent protection involves the use of fuses or circuit breakers to prevent excessive current from flowing through the transformer.
Overvoltage protection involves the use of surge arresters to protect the transformer from voltage spikes.
Differential protection involves the use of relays to detect any difference in current between the primary and secondary coils, which could indicate a fault in the transformer.
Other measures such as temperature monitoring and oil level monitoring are also used to protect transformers.
Transformer protection is important to ensure the reliability and longevity of power systems.
