Overview

The GE UR‑8NV is a Current Transformer / Voltage Transformer (CT/VT) input module designed for the GE Multilin Universal Relay (UR) family. It provides high‑accuracy analog inputs from CTs and VTs, enabling the UR platform to perform advanced protection, control, and monitoring functions for power systems.

By converting analog signals from CTs and VTs into digital data, the UR‑8NV ensures precise measurement of current and voltage, supporting critical protection schemes such as differential, distance, overcurrent, and voltage regulation. Its rugged design and modular architecture make it ideal for utility substations, power generation plants, and heavy industrial facilities.
