Intelligent Digital Protection Relay (IED)

IED is for 25.8kV distribution line that can monitor and control distribution lines through IEC61850 communication. The device is a combined digital protection relay with line protection, measurement, control and monitoring functions. It monitors and control of distribution lines through IEC61850 communication and provides overcurrent protection and precise measurement values for the main and feeder of distribution lines by installing in 25.8kV Class GIS distribution panels.

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.
