Description
The part number G60-U01-AKH-F8L-H67-M8L-P6D-U6D-W6C specifies a configuration for the GE Multilin G60 Generator Protection System (part of the Universal Relay / UR Series family).
Technical Specifications
Product Overview
The GE Multilin G60 is an advanced, high-performance digital relay designed for the comprehensive protection, control, and monitoring of medium-to-large generators, hydro-turbines, and generator-transformer units. Part of the scalable UR (Universal Relay) platform, it prevents damage from internal faults, abnormal operating conditions, and grid disturbances.
Key Features:
-
Comprehensive Protection: Provides complete primary and back-up protection elements, including differential protection, stator and rotor ground faults, loss of excitation, out-of-step, and inadvertent energization.
-
Advanced Monitoring & Metering: Offers continuous real-time data tracking, extensive event recording, waveform capture (fault diagnostics), and phasor measurement capabilities (PMU).
-
Modular UR Architecture: Utilizes a flexible, modular card slot design (represented by the alphanumeric string in the part number) allowing customization of I/O channels, power supplies, and communication protocols.
-
Robust Communications: Integrates seamlessly into modern substation automation networks via redundant Ethernet ports supporting IEC 61850, Modbus, DNP3, and IRIG-B time synchronization.
