Abstract

This paper introduces experimental investigations about the influence of solid free moving particles on a.c. breakdown voltage behaviour: of insulating oil gaps. The experiments and observations have been conducted by means of using suspended metallic and dielectric particles in small oil sphere gaps as well as in sphere-plate gaps. Moreover, another experiments have been carried out using resting free moving conducting particles on a plate in plate-sphere oil gaps. The observed results about the movement of the conducting particles as well as the influence of the particles on breakdown voltage behaviour of the gaps have been recorded and analyzed, Statistical analysis of the breakdown voltage probabilities and the effects of the number of foreign artificial particles have been discussed.
