Wireless lighteing arrester meter

Wireless lighteing arrester meter zinc oxide arrester tester is used to test the full current and resistive current of zinc oxide arrester. According to the comparison of test parameters, it can be judged whether there are dangerous defects such as insulation moisture and valve aging inside the equipment. It can be used for online live testing and production process inspection.

Wireless lighteing arrester meter Zinc oxide arresters are lightning arresters with excellent protective performance. By taking advantage of the excellent nonlinear voltage-current characteristics of zinc oxide, the current flowing through the arresters is extremely small (at the level of microamps or milliamps) under normal working voltage; when an overvoltage occurs, the resistance drops sharply, dissipating the energy of the overvoltage and achieving the protective effect. The difference between this type of arresters and traditional arresters is that it has no discharge gap; instead, the non-linear characteristics of zinc oxide are utilized to play the roles of current diversion and interruption.
