GE UR 8NH CT/VT Module

Product Introduction

The GE UR 8NH CT/VT Module is a high-reliability measurement interface designed for GE UR Series Universal Relay systems. It is used to acquire and process three-phase current and voltage signals from current transformers (CTs) and voltage transformers (VTs), converting them into accurate low-level signals for protection, monitoring, and control applications.

This module is engineered for protection-critical environments where accurate electrical measurement is essential for system stability and fault response. Supporting 1A/5A selectable CT inputs and three-phase measurement capability, the UR 8NH ensures dependable data acquisition for relay protection, substation automation, and power system monitoring. Its robust design and strong isolation characteristics make it suitable for demanding utility and industrial applications.
