About the UR-8HH

The GE Multilin UR-8HH is a CT/VT (Current Transformer/Voltage Transformer) module designed for installation in the Universal Relays (UR) series. This module provides the relay with:

• 1A or 5A ground CT inputs

• Three 1A or 5A phase CT inputs

It enables the relay to scale down current and voltage ratings to levels suitable for accurate system monitoring and data output. This data is critical for the relay’s protective functions and can be reviewed via:

• The relay’s built-in liquid-crystal display (LCD)

• The EnerVista UR software for more efficient data visualization and analysis

EnerVista UR Software

EnerVista UR facilitates efficient configuration and monitoring of the CT/VT module settings, allowing highly customizable protection schemes tailored to unique system requirements. Key features include:

• Intuitive user interface for easy data review

• Viewpoint UR Engineer tool with drag-and-drop environment for rapid relay commissioning and module integration

Installation and Scalability

The Universal Relays series, including the UR-8HH module, is designed with scalability and ease of installation in mind:

• Removable faceplate on both enhanced and basic relay models for easy access to the module bay

• Comprehensive wiring diagrams and manuals provided by Multilin to facilitate proper installation

Frequently Asked Questions

Q: What role does the UR-8HH serve within the Universal Relay T35?
A: The T35 transformer protection system protects main power transformers and up to five downstream feeders. It can operate automatically or be user-configured, providing phase shift compensation, CT ratio matching, and zero-sequence current elimination. The UR-8HH module supports these functions by supplying the necessary scaled CT and VT inputs.

Q: What components make up the UR series Multilin Universal Relays?
A: The UR series includes various modules such as CT/VT modules (e.g., UR-8HH), digital input/output modules, power supplies (sometimes dual), transducer input/output modules, CPUs, inter-relay communication switches, and IEC Process Bus interfaces. These can be customized per user specifications for tailored, advanced protection solutions.
