Description

The General Electric Multilin UR 8GH is a specialized CT/VT (Current Transformer/Voltage Transformer) input module designed for the Universal Relay (UR) platform. This horizontal-mount module provides high-precision signal acquisition for protective relaying applications, featuring a configuration of 4 CT and 4 VT inputs to support complex monitoring and protection schemes within the UR chassis.

Features

  • Designed for integration with the GE Multilin Universal Relay (UR) series.
  • Horizontal chassis mounting configuration.
  • Supports 8 total inputs (4 CT and 4 VT channels).
  • High accuracy measurement suitable for critical power system protection.
  • Wide operating temperature range for demanding industrial environments.
  • Robust isolation to protect internal relay circuitry from transient surges.

Installation Guidelines

  • Ensure the UR chassis is fully de-energized before installing or removing the module.
  • Handle the module using standard ESD (Electrostatic Discharge) precautions to prevent damage to sensitive internal components.
  • Slide the module into the designated horizontal slot of the UR chassis, ensuring the backplane connectors are properly aligned.
  • Secure the module using the integrated locking mechanisms or mounting screws to ensure proper grounding and mechanical stability.
  • Verify that all CT and VT wiring is correctly terminated according to the specific relay wiring diagram to avoid measurement errors or secondary circuit hazards.

FAQ

Q: Is this module compatible with all GE Multilin UR series relays?
A: The UR 8GH is designed for specific UR chassis configurations. Please verify your relay's ordering code and hardware compatibility before installation.

Q: What is the primary function of the UR 8GH?
A: This module serves as the analog interface for the relay, converting high-voltage and high-current inputs from the power system into low-level signals that the processor can analyze for protection and metering.
