Title: Polarity Effects on the Corona and Breakdown of Mixture (SF<sub>6</sub>/N<sub>2</sub>) in a Needle-Plane Gap under Pulse Voltage
Abstract: The polarity effects of the corona and the breakdown characteristics of mixtures (SF 6 /N 2 ) were investigated in the needle-plane gap, using pulses with various rise times. The polarity effects were remarkable both on the corona initiation and breakdown voltages. Several bright spots were seen on the negative needle surface. Negative breakdown voltage, especially under pulses with short rise time, was higher than the positive breakdown voltage.
