1. Product Overview
UR9EV is the core CT/VT acquisition and main CPU processing module of GE Multilin UR modular universal relay protection platform, which is pluggable and installed in the main rack of UR protection relay as the core signal processing unit of the whole protection device.
The module integrates independent high-precision analog sampling circuit, supports 3-phase 1A/5A current transformer input, dedicated ground CT sensitive grounding fault detection, and 4-channel voltage transformer signal acquisition, which can collect three-phase voltage, three-phase current and zero-sequence current data of power grid in real time.
Built-in high-speed industrial processor runs complete power protection algorithms including overcurrent, overvoltage, undervoltage, differential protection, ground fault protection, etc. It has real-time signal integrity self-diagnosis function, which can identify abnormal conditions such as CT open circuit, VT loss of voltage, signal distortion, effectively avoid protection false tripping caused by signal failure.
Equipped with front-panel RJ45 Ethernet port, support Modbus TCP, IEC 61850 and other industrial communication protocols, cooperate with EnerVista Launchpad software to complete parameter configuration, fault wave recording reading, real-time data monitoring and firmware upgrade.
It cannot work independently and must be matched with UR series rack, digital I/O expansion modules and power supply modules to form a complete relay protection device. Widely used in thermal power, petrochemical, substation transmission and distribution power system main equipment protection, belongs to classic legacy spare parts for maintenance and upgrade of old UR protection systems.
