GE UR8FH CT/VT Module

Technical Specifications 

GE Multilin UR8FH is a CT/VT module used with Universal Relay systems for current and voltage signal input. It supports 3-phase current transformer connections, ground current measurement, and four voltage transformer terminals, providing reliable signal acquisition for protection, monitoring, and control applications. The module is suitable for feeder, transformer, generator, and bus protection systems where accurate electrical measurements are required. UR8FH works with existing UR series relay hardware and helps improve measurement performance by converting CT and VT signals into usable data for relay functions. It is commonly used for maintenance and replacement in industrial power systems.

Ground Fault Protection

The UR-8FH is the CT/VT described as having the standard 4CT/4VT. It does not have the sensitive ground feature, which allows the universal relay to be protected on grounded systems that are classified as high-impedance. The modules that have this feature are the UR-8G, UR-8J, UR-8M, and UR-8R order codes. These mentions are of the newer CT/VT generation. There are two older CT/VT modules (UR-8B and UR-8D) which also have the sensitive ground fault protection capability. The standard models with the 4CT/4VT feature for example does have the typical up to 24 analog current transformer and voltage transformer capacity as described of all the CT/VT modules incorporated into the various universal relays.

I/O Module Capabilities

In addition to the CT/VT modules, the universal relays also have a transducer I/O module. This provides the UR with either DCmA cards or RTDs to monitor flow, wind speed, temperature, vibration, or pressure. Analog outputs can also be used to connect the UR to an external PLC or other user interface devices. The universal relays also have a digital I/O module that contains up to 96 contact inputs and up to 64 contact outputs.
