| Abstract: | For the problem of monitoring the state of the Zinc oxide surge arrestors,this paper analyses and discusses the current conditions of the instruments in the respects of measuring ideology and measuring methods.A leakage current sample method based on an optic electronic transmitting and isolating circuit is proposed. This sample not only can isolate the system and the instrument electrically,but also can transmit the analogue signals linearly. |
