Abstract :
Partial discharge (PD) is the most unwanted phenomenon in high voltage insulation system. One of the wellknown types of PD in high voltage insulation is corona discharge. In this work, the characteristics of corona discharges from different types of electrodes (sharp, flat and sphere electrodes) were studied to enhance the understanding of corona discharges. The electrical field distribution for all types of the electrodes was also simulated to study the influence of the field on the PD characteristics. The results show that the characteristics of corona discharges and its electric field distribution are heavily influenced by the shape of the electrodes under high voltage stress.
