What is the protection of transformer?

Question

Accepted Answer

The protection of a transformer involves various measures to ensure its safe and reliable operation.

Overcurrent protection: Protects against excessive current flow.
Overvoltage protection: Guards against high voltage surges.
Under/over frequency protection: Monitors and controls the frequency of the input power.
Temperature protection: Prevents overheating by monitoring the transformer's temperature.
Buchholz relay protection: Detects internal faults such as oil leaks or gas accumulation.
Differential protection: Compares the currents entering and leaving the transformer to detect internal faults.
Ground fault protection: Detects and isolates ground faults to prevent damage.
Short circuit protection: Safeguards against short circuits.
Lightning protection: Shields the transformer from lightning strikes.
Backup protection: Provides redundancy in case primary protection fails.
