What are the Various ways of distribution Transformer protection?

Question

Accepted Answer

Various ways of distribution transformer protection include overcurrent protection, differential protection, and earth fault protection.

Overcurrent protection involves the use of fuses or circuit breakers to protect the transformer from excessive current.
Differential protection compares the current entering and leaving the transformer to detect any internal faults.
Earth fault protection detects any fault between the transformer winding and earth, and trips the circuit to prevent damage.
Other methods include overvoltage protection, underfrequency protection, and thermal protection.
The choice of protection method depends on the type of transformer and the level of protection required.

Accepted Answer

A common method that detects current imbalances between different phases or sections of the windings. Differential relays are often used for transformers with ratings over 10MVA.
