High voltage current sensor

The FR050HV high-voltage current sensor is a portable clamp design using the latest CT technology, designed specifically for online measurement of current, leakage current, high-order harmonic current, phase, electrical energy, power, power factor, and other detection of high and low voltage lines. No need to disconnect the tested line, safe, fast, high-precision, high stability and uninterrupted detection. The sensor adopts an automatic opening and closing structure, with the front push jaw opening to clamp the tested wire, and the rear pull jaw opening to separate from the tested wire, used in conjunction with an insulating rod. Used for testing high-voltage lines of 60kV and below.

It can be used in conjunction with various measuring instruments for measurement, and can also be connected to phase detection analyzers, industrial control devices, data recorders, oscilloscopes, harmonic analyzers, power quality analyzers, high-precision digital multimeters, etc. It has the characteristics of simple use and easy portability. 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. Insulated rods have the characteristics of moisture resistance, high temperature resistance, impact resistance, bending resistance, and high insulation.
