This instrument is used for the measurement and analysis of leakage current of zinc oxide [MOA] arresters. It is mainly used to measure the resistive current, thereby analyzing the degree of aging and moisture absorption of the zinc oxide. On-site live testing complies with the requirements of the People's Republic of China electric power industry standard "DL474.5—92 Guidelines for On-site Insulation Tests - Arrester Tests". It can also be used in laboratories for factory and acceptance tests.
