GE UR8AH CT/VT module

GE UR8AH  CT/VT module

DESCRIPTION

A CT/VT module for the Universal Relays series, General Electric Multilin’s UR-8AH provides the UR relay with 1A/5A Phase CTs, 1A/5A Ground CTs, and 4 Voltage Transformers. Voltage transformers and current transformers scale down the voltage and current values of the power system to values that can be identified and moderated by the Universal Relay. 

Product Overview

Brand: GE (General Electric)

Model: UR8AH

Type: CT/VT (current transformer/voltage transformer) module

Functional Characteristics

Current and voltage measurement:

The module integrates current transformer (CT) and voltage transformer (VT) to accurately measure current and voltage values in the power system.

The measurement data provided can be used for power system monitoring, protection and fault analysis.

Protection functions:

The UR8AH module is equipped with a variety of protection functions, such as differential protection and concurrent phase splitting protection, which enable it to respond quickly to abnormal conditions in the power system, such as short circuits and overloads.

These protection functions help prevent equipment damage and improve the reliability and stability of the power system.

Enhanced diagnostic functions:

Some versions of the UR8AH module have an enhanced diagnostic function that detects faults within the module and issues an alarm.

This is achieved through advanced algorithms and additional analogue hardware channels, ensuring the accuracy and reliability of the analogue measurement channels.

Highly configurable:

The settings of the UR8AH module can be highly modified to suit different protection schemes and application requirements.

Users can adjust the CT/VT settings to create unique protection strategies.

Compatibility and Integration:

The module is compatible with GE's universal relay series and can be easily integrated into existing power protection systems.

It supports a variety of communication protocols and interfaces for easy data exchange and integration with other devices and systems.
