Clamp current sensor

The FR020 clamp shaped current sensor is a high-precision AC current converter designed with a clamp shaped structure, which can be quickly and easily removed and placed freely during use. Its compact size makes it easier to carry and use. Suitable for detecting AC current, leakage current, high-order harmonic current, phase, electrical energy, power, power factor, etc.

It can be used in conjunction with various measuring instruments, such as on-site calibrators for electric energy meters, multifunctional electric energy meters, oscilloscopes, digital multimeters, cable identification devices, cable fault detectors, double clamp grounding resistance testers, double clamp phase volt ammeters, digital current recorders, etc. It can measure and compare various electrical parameters without interruption of power.

Widely used in substations, power plants, industrial and mining enterprises, as well as testing stations and electrical maintenance departments for current detection and field electrical operations.
