Abstract:

The article deals with the conditions of creating a non-reproducible surface of a solid dielectric. For this purpose, it was decided to use the avalanche-streamer mechanism of the discharge of the interelectrode interval. When applied to the interelectrode interval sharply inhomogeneous field is the decay of the corona formed by the electrode of small size, a set of long thin, stochastic «branching» streamers. This ensures the creation of a non-reproducible pattern of the channels of destruction of the paper dielectric. As a result of this work, the minimum voltage and breakdown voltage values were determined to provide the conditions for creating an avalanche-streamer discharge.
