A test system with UWB and UHF detection technologies was developed to measure partial discharge under DC voltage.According to the analysis of defects in oil-paper insulation of converter transformer
six corresponding PD models were designed.The experimental results of PD detection under DC show that the system can exactly detect pulse current waves and UHF PD signals with good stability and repetitiveness under same condition.This research provides a good test platform for study on single pulse current wave
PD pulse sequence and on-line monitoring technology of UHF PD signals under DC voltage.
