The GE Multilin UR8HH Module is a high-performance protection and control module designed for integration with GE’s Multilin UR-series relays.
Here are its key functions and applications:
1. Key Functions of the UR8HH Module
Advanced Protection & Monitoring:
Provides 8 high-speed analog inputs for precise measurement of voltage/current signals in power systems.
Supports differential protection (e.g., transformer/motor protection) with millisecond-level response times.
Seamless System Integration:
Compatible with UR-series relays (e.g., UR6xx, UR8xx) for scalable I/O expansion.
Uses EnerVista UR Setup software for configuration and logic programming.
Industrial Reliability:
Operates in harsh environments (-40°C to +85°C) with EMI/shock resistance.
Complies with IEC 61850 and Modbus for SCADA/EMS communication.
Flexible Control Logic:
Enables custom automation rules (e.g., load shedding, fault isolation).
2. Typical Applications
Power grids: Transformer/busbar protection in substations.
Industrial plants: Motor/generator protection and control.
Renewable energy: Wind/solar farm grid synchronization.
This module ensures high-accuracy protection and real-time control for critical electrical assets.
