Zinc Oxide Arrester Tester is an electrical product that protects various electrical equipment in the power system from overvoltage damage. It has good protective performance. If the zinc oxide arrester has leakage, that is, its performance is reduced and it cannot play a protective role, then testing the performance of the zinc oxide arrester is very important. The main indicator is the leakage current value of the zinc oxide arrester. How to simply and quickly measure this leakage current value?
1. Connect the 5-meter insulating rod;
2. Connect the clamp head of the S290M detector to the upper end of the insulating rod;
3. Turn on the detector clamp head and the detector receiver;
4. Press the open clamp head button on the detector receiver to open the movable end of the detector clamp head jaw;
5. Check the display of the detector receiver to see the clamp head status and communication status;
6. Use the insulating rod to clamp the clamp head onto the grounding wire of the zinc oxide arrester to be tested;
7. Press the close clamp head button on the detector receiver, and check the closing status of the clamp head on the detector receiver;
8. After the clamp head is closed, the instrument can measure whether there is leakage current on the grounding wire of the zinc oxide arrester, and view the leakage current value through the detector receiver;
9. It can be tested with power on, without power outage, without disassembling equipment, and without manual climbing. It is safe, fast, strong anti-interference, and repeatable.
