ZX-MOA Lightning Arrester leakage Current Tester is specially used to detect the internal defects of non-clearance zinc oxide arrester MOA valve with poor electrical contact in power system, and measure the DC reference voltage (U1mA) of MOA and 0.75U1mA leakage current. The instrument is composed of dc high voltage power supply, measurement and control system, all components concentrated in a case, with small volume, light weight and other characteristics, is the power system and zinc oxide arrester production plant field test essential equipment.
1. Automatic measurement, convenient and quick operation
The instrument adopts the automatic control principle of the closed-loop adjustment precision of 1mA current and 0.75 times the DC reference voltage, using microcomputer control measurement process, leakage current DC reference voltage of arrester only needs to measure the Zinc Oxide 1mA press a button to automatically when the DC reference voltage and 0.75 times of the process takes about 15 seconds very suitable for mass measurement.
2. Integrated structure, small volume, light weight
The instrument consists of high voltage power supply, measurement and control system. All the components are concentrated in a case. It has the characteristics of small volume, light weight and so on.
3. Special process design, simple connection
