Product Introduction
The GE UR 8GH CT/VT Module is a specialized measurement interface designed for GE UR Series Horizontal Unit protection and control systems. It is used for acquiring high-accuracy current and voltage signals from current transformers (CTs) and voltage transformers (VTs), with enhanced sensitivity for ground fault detection applications.
This module supports 4 CT inputs and 4 VT inputs, including sensitive ground measurement capability, making it particularly suitable for protection schemes requiring high-resolution fault detection and system stability. It is widely used in power generation, transmission, and industrial electrical systems where precise grounding and phase monitoring are critical for safe operation.
