GE Multilin T60-K03-HKH-F8N-H6D-M8L-P6D-U6B General-purpose Relay

Product Description

GE Multilin T60-K03-HKH-F8N-H6D-M8L-P6D-U6B is a multi-winding transformer protection, measurement & control relay from GE Vernova UR Universal Relay family. This unit adopts horizontal 19-inch rack mounting with enhanced color graphical HMI. Power supply supports 125/250V AC/DC. It is equipped with 8 CT current inputs with enhanced diagnostics, multi-channel digital inputs and Form-A relay outputs. It integrates protection, metering, fault recording, event logging and communication. It implements dual-breakpoint dual-slope percentage differential protection with inrush and overexcitation restraint plus inter-turn fault detection. It serves as primary and backup protection for medium & large power transformers. It supports IEC 61850, GOOSE and IEEE1588 time synchronization. Settings and commissioning can be done locally or remotely via EnerVista software.

Application

Deployed in power substations as primary and backup protection for 2-winding, 3-winding & multi-winding power transformers, autotransformers, phase regulators and reactors.

1. Primary & backup differential protection for main transformers and station service transformers in power plants and substations;
2. Fault detection, tripping, alarming and fault recording for transformers in transmission & distribution power grid;
3. Step-up transformer protection for renewable energy farms (solar & wind power);
4. Transformer protection for industrial captive power plants in metallurgy, petrochemical and water treatment industries;
5. Compatible with complex substation topologies such as ring bus, breaker-and-a-half and double busbar; supports wide-area protection via R-GOOSE.
