GDYZ-301W Metal Oxide Arrester Tester breaks the traditional structure, using high accuracy (1uA) leakage test and the newest CT shielding technology. It is made of special HV detector and HV insulating rod. It can wireless transmit testing data with wireless receiver which can receive testing data in 30m.
GDYZ-301W Metal Oxide Arrester Tester is designed with binding clip and boot sector to test with high accuracy, reliability and stability. The insulating rod is light, dampproof, anti-heat, anti shock, high insulation and flexibility. The instrument can keep and store the testing data.The special HV clip with flexible insulating rod can contact and leave the HV terminal or grounding terminal of the MOA easily and safely.
Attention: The leakage current is below 500uA when the MOA is working(refer to RULES OF ONSITE INSULATING TEST, MOA TEST DL474.5-92, RULE NO.7.1), If the leakage current is above 500uA, the MOA is probably with spot, moisture inside or aging. The bigger the leakage current is, the more serious the problem is. The technicians can deicide to maintenance or remove the MOA to laboratory for test.
