The power clamp meter is used to measure and maintain onsite power devices and power cables. Handheld fixture structure size is small, light weight. Users can carry around, convenient and quick measurement. Power Clamp meter is equipped with powerful measurement and data processing software, can complete the voltage, current, active power, power factor, apparent power, reactive power, energy, frequency, stability performance, operation and other 8 parameters of measurement, calculation and display.
The power clamp meter consists of current transformer and ammeter. The conductor through which the measured current passes can pass through the gap in the opening of the iron core without being cut off, and the iron core will close when the wrench is released. Therefore, the secondary coil is connected. The ammeter will display an indication value indicating the current of the line under test. The power clamp meter can pass through the core of the circuit under test and become the primary coil of the current transformer. Tightening the wrench can open the core of the CT and induce current in the secondary coil through the current.
Power clamp meters were originally used to measure AC current, but now multimeters have some features that can measure AC and DC voltage, current, capacitance, diode, transistor, resistance, temperature, frequency, etc.
The power caliper meter has been carefully designed and manufactured for online online testing of current transformers, transformer primary and secondary circuits, transformer current ratio, ratio difference, Angle difference, phase difference and polarity in 380V/220V distribution systems. ; Current detection is usually carried out in substations, power plants, distribution rooms, industrial and mining enterprises, test stations and electrical maintenance departments.
