Abstract
Compares experimental measurements of the electroinsulation properties of a vacuum insulation system with those of the same system filled with SF6. The influence of the following factors of the condition of the two insulation systems on the electron strength at AC voltage was examined: conditioning, kind of electrode material, level of pressure, the degree of nonuniformity of macroscopic and microscopic electric fields, and temperature. The results of the experiments seem to indicate that the higher the degree of nonuniformity of the macroscopic electric field and the lower the temperature, the more justified is the use of vacuum insulation
