Overcurrent Relay

Relays are protection and control devices installed on transformers or their related circuits. They work by monitoring and controlling electrical parameters in the circuit to ensure the safe operation of the transformer, prevent accidents, and react quickly in case of faults.

Transformer relays act like the ‘smart switch’ and ‘protection guardian’ of the power system. They can both transmit control signals (like relay functions) and monitor and protect electrical parameters, making sure transformers operate safely and stably under all conditions.

Use Cases:

– Power Systems: Main and backup protection for large transformers and substations.

– Industrial Distribution: Overload and short-circuit protection for factory transformers and distribution cabinets.

– New Energy and Charging Stations: Monitor DC voltage and current to keep equipment safe.

– Automation Control: Work with PLCs or microcontrollers for smart protection and status monitoring.
