Product Description

The GE Multilin UR 8HH is a dedicated analog measurement module for the GE Multilin Universal Relay Series. It interfaces with current and voltage transformers (CTs and VTs) to step down high-magnitude primary signals, providing precise 1A/5A phase and ground current measurements.

This accuracy enables the relay to execute protective functions reliably and maintain power system stability.

Operational Features

The UR 8HH integrates seamlessly into the UR chassis, enabling high-fidelity data acquisition. Measurements can be displayed on the relay’s local LCD or exported via EnerVista UR for detailed analysis. The module supports customizable protection schemes, allowing engineers to set site-specific thresholds and monitor system conditions in real time while preserving signal integrity from field sensors to the relay CPU.

FAQ

Can the UR 8HH be configured for different CT ratios?
Yes. The module supports programmable CT/VT scaling through EnerVista UR, allowing adaptation to various primary sensor ratings.

Is this module hot-swappable?
No. Always de-energize the relay rack and follow lockout/tagout procedures before inserting or removing the UR 8HH to prevent electrical hazards and bus communication errors.
