Feature:
1. The zinc oxide arrester DC parameter tester is fully automated, easy to operate, and the fast-changing zinc orthodor DC parameter tester uses automatic control principles to accurately closed-loop adjustment of 1mA current and 0.75 times the flow reference voltage, using microcomputer control measurement process, Just pressing a button to automatically measure the DC reference voltage at 1mA of the zinc oxide arrester and the leak current under the 0.75 times DC reference voltage, the entire process takes only 15 seconds, which is very suitable for bulk measurements;
2. Integrated structure, small size, weight of the zinc oxide arrester DC parameter tester integrates DC high voltage power supply, measurement, and control system, all components are concentrated in a chassis, have the characteristics of small volume, light weight.
3. The zinc oxide arrester DC parameter tester special process design is simple.
