Effect of Floating Objects on Critical Impulse Breakdown of Air

A. Settaouti and L. Settaouti

Abstract:
The characteristics of breakdown voltages against the position of floating metallic particles in atmospheric air are investigated experimentally to provide fundamental parameters determining the breakdown voltage in the presence of floating objects around high voltage power apparatus by an air insulation. Experimental results show that the main factors affecting the breakdown voltage are the shape and the size of floating objects, the object location and the gap length. The possible mechanism by which the local spark initiates the main breakdown would seem to be associated with the high electric field around the local spark channel enhanced by unnecessary streamers protruding from its surface. The model is in excellent agreement with experiment results.
