The zinc oxide arrester tester is used for the measurement and analysis of zinc oxide [MOA] leakage current. It is mainly used to measure resistive current to analyze the degree of zinc oxide aging and moisture. The on-site live test conforms to the essentials of the People’s Republic of China Electric Power Industry Standard "DL474.5-92 Implementation Guidelines for Site Insulation Tests-Lightning Arrester Test" It can also be used in the laboratory to make factory and acceptance tests.

1. Large-screen LCD display, full Chinese menu operation, easy to use.

2. High-precision sampling processing circuit and Fourier harmonic analysis technology ensure more reliable data.

3. The instrument uses a unique high-speed magnetically isolated digital sensor to directly collect the input voltage and current signals to ensure the reliability and safety of the data.
