Cast-resin dry-type transformer partial discharge signal analysis using spectral correlated empirical mode decomposition method

Abstract

Cast-resin dry-type transformers are widely used in high power applications. Long-term operation increases the extent of damages if no proper safeguards are taken. The major cause of transformer damages is insulation deterioration, which is correlated with partial discharge (PD) occurrence. Recent PD research studies have focused on how to locate the PD… (More)
