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.

Technical Specifications

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.
