NDZnO-201 Zinc Oxide Arrester Characteristic Tester

Product Introduction

       This instrument is used for the measurement and analysis of leakage current in zinc oxide [MOA]. It is primarily employed to measure resistive current, thereby analyzing the degree of aging and moisture absorption in zinc oxide. On-site live testing complies with the requirements of the power industry standard "DL474.5—92 Guide for On-Site Insulation Tests—Surge Arrester Tests". It can also be used for factory and acceptance testing in laboratories.
