Product Description:

The UR-8LH, manufactured by General Electric Multilin, is a CT/VT (Current Transformer/Voltage Transformer) module designed for the Universal Relay series. This module serves the purpose of either replacing existing modules, upgrading current ones, or providing additional capabilities to Universal Relays that were not originally equipped with this specific module. The UR-8LH offers the relay 4 CT and 4 VT inputs along with enhanced diagnostic functionality.

The unique feature of the UR-8LH is its advanced diagnostic capabilities, which bring several advantages to the power system. Primarily, this module has the ability to verify the integrity of analog signals, ensuring system reliability. It accomplishes this through the use of a sophisticated algorithm that assesses the proper functioning of the analog signals.

CT/VT transformers play a crucial role in scaling down current and voltage values to levels compatible with the relay, thus calculating ratios that provide information related to current and voltage. This function is critical for identifying potentially hazardous voltage and current conditions within the system and determining the appropriate response. The data generated by this module can be viewed through the liquid-crystal display on the front faceplate or via a computer running the EnerVista UR software program.

Frequently Asked Questions about UR-8LH:

Q: What is a UR-8LH?

A: A UR-8LH is a CT/VT module (Current Transformer/Voltage Transformer) found within certain universal relays. Each universal relay consists of several components, including a CT/VT module, a CPU, a power supply, an IEC Process Bus, inter-relay communications, a communication switch, digital I/O, and transducer I/O. The CT/VT module is responsible for monitoring the AC power lines and can accommodate up to 24 signals. Some CT/VT modules are equipped with a sensitive ground input for ground fault protection. The order code designation indicates whether the unit has this feature. The Multilin UR-8LH offers standard 4 CT/4 VT characteristics but with enhanced diagnostic features. Modules such as 8G, 8J, 8M, and 8R also provide sensitive ground fault protection. To avoid hardware mismatch errors, the UR-8LH, being a new module, should be paired with a new CPU. Firmware versions of at least 4.0x are compatible with the new CPUs and the new CT/VT modules. In contrast, universal relays with firmware versions of 3.4x or older are required for compatibility with older CPUs and CT/VT modules.
