To validate the 7UT82 settings using a 3-phase relay test set (e.g., Omicron, Megger), follow this standard procedure:

Integrated switching control for circuit breakers and disconnectors IEC 61850, Modbus TCP, DNP3, IEC 60870-5-103 PC Software Interface DIGSI 5 Configuration Environment To download the most recent manuals, visit the

Verify the polarity of the CT connections. If a CT is reversed, the relay will interpret normal load current as an internal fault, resulting in an immediate trip upon energization. Check the operational measured values matrix on the display screen to ensure the differential current ( Idiffcap I sub d i f f end-sub ) is near zero under balanced load conditions. Analyzing Fault Records
