GE UR8NH 8‑Channel CT/VT Module (Multilin UR Series)
Manufacturer: GE Multilin / General Electric
Model: UR8NH
Series: Multilin UR (Universal Relay)
Type: 8‑Channel CT/VT Analog Input Module
Function: High‑precision AC current/voltage acquisition for protection & metering
1. Overview
The GE UR8NH is a **high‑density 8‑channel CT/VT input module** for the GE Multilin UR series protection relays. It provides 8 isolated analog input channels for connecting current transformers (CTs) and voltage transformers (VTs), supporting both 1A and 5A secondary CT ratings. Designed for utility substations and industrial power systems, it delivers accurate, high‑speed waveform data for protection, metering, and power quality monitoring, with advanced onboard diagnostics.
