Abstract
The characteristics of the positive leader propagation in the inverted rod-plane gap are investigated in this paper. The discharge experiments in a 3-m inverted rod-plane gap were carried out under switching impulse voltage. The positive leader propagation process was recorded by using a high speed CCD camera. The aspects to describe the positive leader propagation characteristics of the inverted rod-plane gaps are obtained and compared with the traditional rod-plane gaps. The critical corona radius and continuous leader inception voltage of rod derived in the 3-m inverted rod-plane gap are lower than that of the traditional rod-plane gaps.
