The 220vdc power supply is designed for switching devices and protection relays in the Thermal Power Plant, such as terminal circuit breakers, 10kV circuit breakers, generator/transformer/10kV equipment protection relays,etc.

These critical DC power supply systems are also designed with redundancy features to ensure the plant’s safety under all conditions (normal operation or fault scenarios).
