GE UR8LH Universal Relay Series features CT/VT modules

Product Description
The UR-8LH from General Electric Multilin is a CT/VT module designed for the General Relay series. This module can be used to replace existing modules, upgrade current modules, or provide new capabilities to General Relays that were not originally equipped with the given module. This special module offers 4CT/4VT to the relay and features enhanced diagnostic functions.
The variant of this module, UR-8LH, is equipped with enhanced diagnostic capabilities, offering numerous benefits to the power system. Firstly, this module can verify the integrity of analog signals and ensure their reliability. It achieves this by employing an advanced algorithm to determine whether the signals are functioning properly.
The CT/VT transformer scales down the current and voltage values proportionally to the level that the relay can handle, allowing it to calculate a ratio and output values related to the current and voltage. This feature is crucial for identifying dangerous voltage and current conditions within the system and establishing an appropriate response. These data can be viewed on the front panel’s LCD display or on a computer running the EnerVista UR software program.

The GE UR8LH is a CT/VT (current transformer / voltage transformer) module produced by GE Multilin, mainly used in the General Relay Series. The relevant introduction is as follows:
