摘要：

Partial discharge (PD) induced by the presence of free multiple spherical metal particles in two commercial transformer oils has been measured at ambient temperature and at 40 degrees C in order to develop an effective monitoring system for high voltage transformer. The PD measurement result of a conventional mineral oil has been compared with vegetable-based transformer oil of Palm Fatty Acid Ester (PFAE) under AC applied voltage in quasi-uniform field at three consecutive gaps of 5mm until 9mm. Three different electric field of 1.5kV/mm, 2kV/mm and 2.5kV/mm has been applied at each gap in the PD measurement. The partial discharge inception voltage (PDIV) was measured to be 6.7kV and 8kV for PFAE and mineral oil at 9mm gap respectively. The Phase-Resolved Partial Discharge (PRPD) of PFAE and mineral oil at 1.5kV/mm until 2.5kV/mm appeared to have a distinctive characteristic at these different temperatures.
