INTRODUCTION

MEWOI1100D Zinc Oxide Arrester Leakage Tester has unique features of automatic plug function, specially designed and manufactured for high voltage current measurement; use the latest CT technology and integrated mask digital technology; composed of special high voltage detector, wireless receiver and high voltage insulation rods. Wireless transmission can receive the measured data by penetrating storey building barriers or 30 meters.The integrated design of clamp and lead zone of MEWOI1100D Zinc Oxide Arrester Leakage Testerensures uninterrupted year-round high precision, high reliability and high stability test.

In general cases, the leakage current of Zinc Oxide Arrester should be less than 500uA. Can judge the operation of lightning arrester lightning arrester leakage according to the test, if measured lightning arrester leakage current is too large, more than 500uA, excluding the system voltage is too high, then the arrester may have dirt or moisture or aging, the larger the leakage current, more serious of dirt or moisture or aging. The leakage current to be a importance reference to the maintenance department to find the power transmission problem, or to check whether an  arrester should be unstalled to under testing in lab or replace, avoid unnecessary replacement.
