Air insulation is widely used as the external insulation of power transmission lines. The performance of air insulation is a concern. The breakdown voltage of rod-plane air insulation with a certain length is often used to evaluate the performance of the air insulation with the length. The breakdown voltage of rod-plane air insulation is determined by the discharge phase termed breakdown phase. The breakdown phase of a 4 m rod-plane air insulation under positive standard switch impulse voltages was recorded by a high-speed camera and reported in this paper. The breakdown phase would help to deepen the understanding of air insulation.
