The YTC620B Zinc Oxide Surge Arrester DC Parameter Tester is specifically designed to detect internal defects in the MOA valve of gapless zinc oxide surge arresters used in 10kV and below power systems. According to the provisions of 14.2 in the "Preventive Test Code for Power Equipment" DL/T596-1996, power plants and substations should perform DC 1mA voltage (U1mA) and leakage current detection at 0.75 U1mA for metal oxide surge arresters before and when necessary during the thunderstorm season each year.

Product nickname:Zinc oxide lightning arrester tester, zinc oxide lightning arrester characteristic tester, zinc oxide lightning arrester DC parameter tester.
