Dissociation and suppressing interference are always crucial for partial discharge live and on-line detection for substation equipment, so it is necessary to research on interference signal feature for substation in different places, in order to achieve on separating true partial discharge from interference signal. This paper proposes, which takes 110kV, 220kV and 500kV substation as research objects,...
Internal insulation defects of oil-immersed transformers are common because of flaws in both manufacturing and transportation process. Partial discharge (PD) activity caused by insulation defects may occur at rated voltage condition, leading to deterioration of material, which results in breakdown of insulation. Feature parameters of PD are closely related to the performance of insulation materials...
