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;
