Product Introduction
The GE UR 8FV CT/VT Module is a high-reliability measurement and signal acquisition module designed for GE UR Series Universal Relay systems. It is used to interface with current transformers (CTs) and voltage transformers (VTs), converting high-voltage and high-current signals into accurate, low-level signals for protection, monitoring, and control functions.
This module is engineered for protection-grade electrical measurement, supporting both phase and ground current inputs along with a four-terminal voltage transformer configuration. It plays a critical role in ensuring accurate system visibility for protection relays, power monitoring, and fault detection. Designed for demanding electrical environments, the UR 8FV provides stable performance, strong isolation, and high measurement accuracy, making it suitable for utility, industrial, and power generation applications.
