GE T60-K03-HKH-F8N-H6D-M8L-P6D-U6B Transformer Protection Relay

GE T60-K03-HKH-F8N-H6D-M8L-P6D-U6B is a UR-series digital transformer protection relay made by GE Multilin (GE Vernova). It delivers differential protection, overcurrent, overvoltage and thermal monitoring for power transformers, integrating protection, metering, control and fault recording in one single panel-mounted unit.

This relay adopts FlexLogic programmable logic, supports Ethernet, RS485 and multiple substation communication protocols. It can calculate transformer hot-spot temperature and loss-of-life aging data, widely used in power grid substation, power plant and industrial substation transformer cabinet spare replacement and upgrade projects.
