MSBL-IV Zinc Oxide Surge Arrester Tester
The zinc oxide lightning arrester tester is a specialized instrument used to test the electrical performance of zinc oxide lightning arresters.
This instrument is suitable for live or power-off detection of zinc oxide lightning arresters of various voltage levels, so as to timely detect dangerous defects such as insulation moisture and valve plate aging inside the equipment.
main features
1. It is possible to measure the resistive current of three-phase lightning arresters simultaneously.
2. Measure the full current, resistive current and its harmonics, power frequency voltage, active power and phase difference of zinc oxide lightning arrester.
3. The instrument has anti-interference and automatic compensation functions.
4. It has functions such as resistive current fundamental peak output and edge phase correction.
5. Large screen LCD display, fully Chinese menu operation, easy to use.
6. The instrument is equipped with rechargeable batteries, calendar clock, and micro printer.
7. Can store measurement data.
