Product Description
GE UR8LH
The GE UR8LH is a high-performance Line Differential Relay, a key component of the Multilin Universal Relay (UR) platform. Designed for the comprehensive protection of transmission and sub-transmission lines, the UR8LH provides secure and reliable operation for critical power system assets. It employs a sophisticated phase-segregated differential algorithm for high-speed fault detection and tripping, ensuring minimal system disruption. The UR8LH is capable of protecting multi-terminal lines with up to six terminals and integrates a full suite of backup protection functions, including distance, overcurrent, and breaker failure protection. Its modular design allows for flexibility in configuration and easy maintenance, making it a versatile solution for a wide range of line protection applications.
Technical Specifications:
- Protection Functions: Phase-segregated line differential (87L), phase distance (21), directional overcurrent (67), breaker failure (50BF)
- Application: High-speed protection for 2, 3, 4, 5, and 6 terminal transmission and sub-transmission lines
- Communication Protocols: IEC 61850, DNP 3.0, Modbus RTU/TCP, IEC 60870-5-103/104
- Communication Channels: Direct fiber, SONET/SDH (G.703, C37.94), IEEE 1613 compliant Ethernet
