Product Details

Rogowski Coil Current Sensor / Instrument Current Transformer

 

1 Apply to
«24kV insulated cable busbar
≤0.72kV low voltage noninsulated busbar
2 Application
♦ Current sensor apply to current measurement of cable busbar & insulation bushing of low voltage I medium voltage C-GIS switchgear in smart grid ; ♦ Current sensor should be mounted on the insulated cable, shielded cable connector, or any other type of insulated conductor.

 

3.

Features:
Rogowski coil current sensor provides a reliable alternative solution for protecting, measuring and monitoring medium voltage distribution networks. Its high performance and compact size are more suitable for medium voltage switch optimization design, thereby improving the protection, measurement and monitoring functions.
♦ Excellent linearity, high precision, stable and reliable;
♦ No need field calibration.
♦ Without high voltage danger when open circuit at secondary.
♦ No iron core saturation or damage in the event of overload;
♦Open-close structure, flexible, lightweight, beautiful appearance;
♦Small size and lightweight, suitable for new installation and remodeling;
