I  Introduction

the MOA characteristic tester is used for the measurement and analysis of metal oxide arrester [MOA] leakage. Widely use in measuring the resistive Current to analyze the degree of zinc oxide  arrester field  Monitor and test in Lab.this tester adopts microcomputer sampling, control and other advanced Technology, IT can test  zinc oxide Arrester in the power frequency voltage of the full current, third harmonic, Resistive current, resistive current peak, capacitive current, active power, Etc..and display voltage, current waveform and print out test data. At the same Time provide the field waveform display.The instrument has the characteristics of simple connection, high measuring accuracy and strong reliability.The Instrument is small in size and light in weight, and adopts integrated design, Which is easy to carry and operate in the field.   

II Performance
