Research on EMC Tests of Intelligent Monitoring Devices for Metal-Oxide Surge Arresters

According to the structure and working principle of metal-oxide surge arrester (OMA) intelligent monitoring device (IMD), this paper analyses the electromagnetic environment of it and obtains the importance and necessity of studying electromagnetic compatibility(EMC) tests. As there is no testing standard basis for the IMD, in this paper the corresponding EMC test requirements, test parameters and test methods are given. Aiming at the problems of the IMD during the EMC tests, the practical anti-interference measures are given to ensure the reliability of the design at the end of the paper. By improving the EMC performance of IMD, the reliability of IMD in harsh high-voltage electromagnetic environment can be ensured. Beyond that, this paper also offers reference for establishing testing standards of the IMD.
