FAQs

  • What is the UR-8LH?+
    The GE Multilin UR-8LH is a modular CT/VT input module for the Universal Relay (UR) series, providing 4 Current Transformers (CT) and 4 Voltage Transformers (VT) with enhanced diagnostics
  • What is the primary function of the UR-8LH module?+
    The UR-8LH acts as a signal interface module, scaling down high current/voltage values from the power system to levels safe for the UR relay to measure. It includes enhanced diagnostic features to verify analog signal integrity.
  • Does the UR-8LH include sensitive ground fault protection?+
    No, while the UR-8LH has advanced diagnostic capabilities, it does not include the sensitive ground fault feature found in other CT/VT modules like the UR-8G, 8J, 8M, or 8R.
  • What is the required firmware/CPU for the UR-8LH?+
    The UR-8LH requires compatible CPUs and is typically used with firmware version 4.0x or newer to ensure proper functionality.
  • Can I swap this module while the relay is powered on?+
    Yes, the GE Multilin UR-8LH supports hot-swapping, allowing for removal or addition of the module without powering down the entire relay, facilitating easier maintenance.

Features:

  • GE Multilin UR Series
  • CT/VT Input Module
  • High-accuracy metering, diagnostics, and data logging
General Electric Multilin's UR-8LH is a CT/VT module desianed for the Universal Relav series.The module can be used to replace current modules, upgrade current modules, or provide new capabilities to Universal Relays that did not originally come with the given module. This particular module supplies the relay with 4CT/4VT with enhanced diagnostics.

This variation of the module, the UR-8LH, is equipped with enhanced diagnostic capabilities that provide a number of benefits to the power system. Primarily, the module is able to verify the integrity of analog signals and ensure reliability. The module does so by employing an advanced algorithm that can determine whether the signals are operating properly.

CT/VT transformers scale down current values and voltage values to amounts that the relay can handle, allowing it to calculate a ratio that outputs values pertaining to current and voltage.This feature is extremely critical for identifying hazardous voltage and current conditions within the system and establishing a suitable response. This data can be viewed through the front faceplate's liquid-crystal display or through a computer running the EnerVista UR software program.

The UR-8LH General Electric CT/VT Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Power Down: Always disconnect the power supply to the relay chassis before removing or inserting modules to prevent damage to the backplane.
Module Insertion: Align the module with the internal guide rails of the chosen slot and push firmly until the connector seats into the backplane.
Secure the Handle: Tighten the self-captive screws on the draw-out handle to ensure the module is locked in place and grounded correctly.
Terminal Wiring: Connect your 4 Current Transformer (CT) and 4 Voltage Transformer (VT) secondary wires to the designated terminal block on the rear of the module.
