Abstract
The article focuses on the interference problem of simulated signals in relay protection devices caused by power frequency magnetic field immunity tests.The testing method of power frequency magnetic field is explained,and the interference mechanism of interference magnetic field on simulated signal circuit is analyzed through simulation.An improvement measure for simulated signal anti-interference is proposed,and the effectiveness of this measure in improving the anti magnetic field interference of simulated signal acquisition circuit is verified through experiments.
