Overcurrent protection safeguards transformers from excessive current due to external faults. It operates by detecting abnormal current levels and isolating the transformer to prevent overheating and potential damage, ensuring system stability.

Overcurrent Protection

Differential protection is a key method used to detect internal faults within a transformer. It compares the current entering and leaving the transformer, tripping the circuit breaker if a discrepancy is detected, indicating a fault.

Differential Protection

The Buchholz relay is a gas-actuated protection device used in oil-filled transformers. It detects gas accumulation or oil movement caused by internal faults, triggering an alarm or tripping the circuit breaker to prevent transformer damage.

Overload Protection

Overload protection protects transformers from prolonged overcurrent conditions that can cause overheating. This system typically uses temperature sensors to monitor winding temperatures, activating cooling systems or tripping the circuit to prevent insulation failure.
