Functional Description
UR8FH is a professional high-precision CT/VT interface module developed by GE, belonging to the core functional expansion unit of the Multilin UR series universal relay system. The module is specially designed for power system protection, monitoring and measurement scenarios, dedicated to converting high-current and high-voltage field signals into low-level measurable signals that relay equipment can identify and process. As a key signal conversion and acquisition medium between primary power equipment and secondary protection relays, the UR8FH module ensures accurate collection, stable conversion and real-time transmission of power system current and voltage data. With industrial-grade precision sampling design and strong environmental adaptability, it supports long-term stable operation in high-interference power plant, substation and power distribution environments, providing reliable data basis for power system protection action, electrical parameter monitoring and fault analysis, and guaranteeing the safe and stable operation of the entire power automation system.
Features
The GE UR8FH CT/VT Interface Module is a dedicated signal sampling and conversion expansion component for GE Multilin UR series protection relays, focusing on high-precision acquisition and isolation conversion of power system current and voltage signals. The module is equipped with complete signal sampling terminals, including 3 channels of 1A/5A phase current CT sampling interfaces, 1 channel of 1A/5A grounding current CT sampling interface and 4 groups of voltage transformer VT input terminals, which can fully meet the comprehensive electrical signal collection requirements of various industrial power distribution systems, substation primary and secondary power systems.
In terms of sampling performance, the UR8FH module adopts high-precision transformer isolation design, which can accurately reduce high-current and high-voltage signals to standard low-level signals suitable for relay processing, effectively avoiding high-voltage and high-current impact damage to the main relay equipment. It features excellent signal stability and linear sampling accuracy, ensuring that the collected electrical parameters are consistent with the actual operating state of the power system, avoiding protection misoperation or refusal caused by signal deviation. The module supports a wide industrial temperature range of -40℃ to +70℃, adapting to harsh outdoor and indoor power operation environments, with outstanding anti-electromagnetic interference and anti-surge capabilities to adapt to complex power field interference scenarios.
The module is perfectly compatible with GE exclusive EnerVista UR configuration software, supporting one-click parameter calibration, sampling ratio setting, signal status monitoring and data logging. It can realize real-time viewing of field current and voltage operating data, convenient for equipment debugging, daily operation inspection and fault troubleshooting. In terms of system compatibility, it seamlessly matches all models of GE UR series universal relays, supports hot-swappable replacement design, and can complete module replacement without shutting down the entire system, greatly reducing equipment maintenance downtime and improving the continuous operation rate of the power system.
The UR8FH module has reliable safety and expandability. Its built-in signal isolation and overvoltage and overcurrent protection mechanisms can effectively isolate field abnormal signals and protect the rear relay and automation equipment. The reserved extended circuit area supports customized functional expansion according to on-site working conditions, which can meet the personalized transformation needs of different power engineering projects. It can effectively expand the signal sampling range and precision of the UR relay system, optimize the system’s power parameter monitoring and protection capability, and improve the overall intelligence and reliability of power system operation and maintenance.
