In a strong electromagnetic environment, most of the current anti-interference methods for partial discharge signals of electronic transformers use digital notch filter, which has poor adaptability and stability. This article studies the source of interference and its impact on partial discharge detection, and has accumulated a relatively complete partial discharge sample database. On this basis, a high-performance arbitrary waveform generator is proposed to restore typical partial discharges, and a platform for quantitatively evaluating the anti-electromagnetic interference capability of partial discharge UHF detection devices through interference simulation is established. Experimental results show that the proposed method has high anti-interference performance.
