【 摘 要 】

In this work, comparison studies of partial discharge (PD) behaviours within palm oil-based Fe2O3nanofluids under AC voltage were performed. The samples were prepared with different weight percentage of Fe2O3nanoparticles; LC (Low Concentration), MC (Medium Concentration) and HC (High Concentration) in order to investigate the electron trapping" effectiveness, their discharge withstand capability, discharge numbers, magnitude and Phase Resolved Partial Discharge (PRPD) patterns under high voltage stress. The results indicate that the presence of Fe2O3nanoparticles with LC enhances the withstand characteristics of palm oil against PD.
