Overview

The GE UR‑8GH Module is part of the GE Multilin UR Series, a family of intelligent relays and modules designed for electrical power system protection. The UR‑8GH functions specifically as a CT/VT (Current Transformer / Voltage Transformer) Ground Protection Module, enabling accurate measurement, monitoring, and fault detection in high-voltage networks.

This module is widely deployed in power generation, transmission, and distribution systems, where reliable ground fault detection and breaker control are essential. It integrates seamlessly with GE Mark VI turbine control systems and is also compatible with FANUC PLC series modules (such as IS215 and DS200), ensuring broad adaptability in industrial automation environments.
