GE UR8LH CT/VT Module

Technical Specifications 

UR8LH CT/VT Module is a GE Multilin Universal Relay input module used for current and voltage signal acquisition in power protection systems. It provides a 4CT/4VT configuration with three-phase current inputs, one ground current input, and four voltage input channels for electrical measurement. The module supports phase CT inputs rated at 1A or 5A, ground CT inputs rated at 1A or 5A, and VT inputs rated from 50V to 240V with 50/60Hz frequency operation. It supports flexible system integration through modular installation and works with EnerVista software for configuration and maintenance. It is widely used in substations, industrial power systems, and automation applications requiring reliable CT/VT measurement.

Detects internal CT/VT channel measurement failures.
Generates alarms when analog input problems are detected.
Blocks related protection actions during detected measurement faults.
Transfers processed measurement data to the relay CPU module.
Supports current, voltage, frequency, and phase measurement functions.
Provides data for protection, monitoring, and control operations.
