Research on Method of Immunity Test of Loaded Electromagnetic Compatibility of Electric Energy Meter Based on Isolation Technology

According to the analysis of the requirements of the equipment application experiment, it can be seen that the equipment requirements and application methods of electromagnetic compatibility conduction anti-interference degree experiment are similar, so the electricity meter inspection device will be used as auxiliary equipment. In practice, the power supply and error processor of the device will be affected by the interference signal transmitted by the system, and the phenomenon of crash and digital jumping will occur in the process of experimental operation, which can not run normally during the working period. By using the filtering technology, the conduction interference in the system can be controlled comprehensively, which can ensure the orderly completion of the experiment and exploration work of the electricity meter inspection device. Therefore, in this paper, based on the understanding of electromagnetic compatibility and electricity meter application detection technology, according to the electromagnetic compatibility test method of electricity meter, the design of the corresponding experimental system, and finally the application performance of the system for practical verification analysis.
