ES050HV high voltage clamp current sensor is a portable clamp design using the latest CT technology. It is specially designed for online measurement of current, leakage current, high harmonic current, phase, electric energy, power, power factor, etc. of high and low voltage lines. No need to disconnect the line under test, safe, fast, high-precision, high-stability and uninterrupted detection. The sensor adopts an automatic opening and closing structure, and the jaws are pushed forward to open and clamp the conductor under test, and the jaws are pulled back to open and leave the conductor under test, and are used in conjunction with the insulating rod. For high-voltage line testing of 60kV and below.
ES050HV can be used with a variety of measuring instruments for measurement, and can also be connected to phase detection analyzers, industrial control devices, data recorders, oscilloscopes, harmonic analyzers, power quality analyzers, and high-precision digital multimeters. It is easy to use and easy to carry. Widely used in substations, power plants, industrial and mining enterprises, testing stations, electrical maintenance departments for current testing and field electrical work. The insulating rod has the characteristics of moisture resistance, high temperature resistance, impact resistance, bending resistance, high insulation, etc.
FR050HV high voltage clamp current sensor is a portable clamp design using the latest CT technology. It is designed to measure the current, leakage current, high harmonic current, phase, electric energy, power, power factor of high and low voltage lines, etc. It is not necessary to disconnect the circuit under test. It is safe, fast, high-precision, and highly stable without interruption. The sensor adopts an automatic opening and closing structure. The front pushing jaw opens and clamps the measured wire, and the back pulling jaw opens to leave the measured wire, used with the insulating rod and for high voltage line test of 60KV and below. It can measure with a variety of measuring instruments, and can also be connected to phase detection analyzers, industrial control devices, data loggers, oscilloscopes, harmonic analyzers, power quality analyzers, high-precision digital multimeters, and more.
