Excellent PLC
Product Introduction
The GE UR 8LH CT/VT Module is a specialized measurement interface designed for GE Mark VI Horizontal Unit (UR Series) control systems. It is used to acquire and process electrical signals from current transformers (CTs) and voltage transformers (VTs), providing accurate real-time data for monitoring, protection, and control applications.
This module plays a critical role in power system measurement by converting high-level current and voltage signals into values suitable for control system processing. It supports both phase and ground current measurements, along with three-phase voltage inputs, ensuring comprehensive electrical parameter monitoring. Built for industrial reliability, the UR 8LH is widely used in power generation, distribution systems, and protection schemes where precision and stability are essential.
