0-30KV Zinc oxide arrester leakage current tester/Zinc oxide arrester DC parameter tester
It is used to detect the internal defects of the poor electrical contact between the MOA valves of the non-gap zinc oxide arrester for power systems of 10kV and below, and measure the direct current reference voltage (U1mA) and the leakage current under 0.75U1mA of the MOA. The instrument integrates DC high-voltage power supply, measurement and control system, and the components are concentrated in a chassis, which has the characteristics of small volume and light weight.
It is mainly used for DC voltage withstand test of zinc oxide arrester, power cable, transformer, generator and other high voltage electrical equipment in power department, industry and mining, metallurgy, steel and other enterprises.

Product characteristics
1, the automatic control principle of 1mA current and 0.75 times DC reference voltage precision closed-loop adjustment, so as to obtain a stable 1mA current when the DC reference voltage and 0.75 times DC reference voltage leakage current.
2, the use of microcomputer control measurement process, the complex manual adjustment process automation, only need to press a button can automatically measure the zinc oxide arrester 1mA DC reference voltage and 0.75 times the DC reference voltage leakage current, the process only 5 seconds, very suitable for batch measurement.
3, the use of digital tube display, in a variety of light conditions can clearly view the measurement data.
4. The combination of high efficiency inverter circuit with high inverter frequency and linear voltage adjustment greatly reduces the volume and weight of the instrument, which is very convenient to carry.
5, only in the measurement process there is a high voltage output, after the measurement is completed automatically cut the high voltage, and can timely display the residual voltage at both ends of the arrester, to give the operator an indication to ensure that the residual voltage at both ends of the arrester is zero before taking the arrester. Automatically cut the high voltage output when overvoltage occurs, and give a prompt.
