Protection Relay

The IED for transformer is a combined digital protection relay with transformer protection and measurement functions. It provides protection elements and precise measurement value for ratio differential and overcurrent in case of internal accident of transformers, and controls transformer monitoring and breaker through IEC61850 communication.
