چکیده
Abstract The article explores the performance of new silicon photoelectric sensor in partial discharge detection, and compares measured optical pulse with traditional UHF pulse. Through electrical synchronous experiments, analyzes discusses detection performance, working characteristics statistical various sensors, advantages feasibility sensors actual monitoring; In addition, two physical phenomena light radiation electromagnetic was obtained through analysis monitoring data. Compared sensor, under optimal voltage has a higher signal-to-noise ratio (SNR); Under interference high-frequency motor, exhibits better anti-electromagnetic ability; Discharge phase interval reflected by PRPD methods maintain good consistency; Pulse repetition rate same trend applied voltage, but frequency pulses is than that because SNR single-photon sensitivity.
