GE UR8FV universal relay CT/VT module

Functional characteristics:

Precise measurement: It can provide 3-1A/5A phase CT, 1A/5A ground CT and four-terminal voltage transformer for the relay, which can precisely measure current and voltage to ensure the effective operation of the electrical system. The current measurement accuracy can reach ±0.5% FS, and the voltage measurement accuracy is ±0.2% FS.

Signal monitoring: It can support up to 24 CT and VT analog signals, enhancing the monitoring capability of power lines. It can also detect faults caused by the condition of grounding conductors. Some modules have sensitive grounding protection functions. For high-impedance grounding systems, grounding fault protection can be achieved by obtaining sensitive grounding inputs.

Good compatibility: Designed to replace old modules or upgrade existing general-purpose relay systems, it is compatible with both new and old general-purpose relays. However, it is necessary to match the module with the corresponding CPU model to avoid incorrect indications on the display screen.

Technical parameters:

Input range: The input of the current transformer (CT) is 1A or 5A, and the input of the voltage transformer (VT) can support 115V, 230V, 460V or 575V.
