Pulse-Type interference suppression based on an improved wavelet threshold for wideband partial discharge detection in transformers

Pulse-type interference at high-voltage (HV) and ultra-high voltage (UHV) transformer sites severely limits the effectiveness of partial discharge (PD) detection, as conventional pulse current measurement below 1 MHz leaves 12-pulse ripple, corona, and electronic switching pulses overlapping with genuine PD signals in...

Dual-sensor correlation for wideband HFCT partial discharge detection and interference suppression in transformers

On-site partial discharge (PD) detection of power transformers is challenged by strong electromagnetic interferences, including converter pulsation, corona, and power-side harmonics, whose spectra overlap with PD signals. A dual-channel synchronous detection system based on self-developed wideband high-frequency curren...
