The paper specifies the results of the tests on electric strength of vacuum, sulphur hexafluoride (SF₆) and the insulation mineral oil under alternate voltage. The tests have been carried out for planar electrodes made of stainless steel or aluminum. It was found that 10^-3 Pa vacuum, 3 10⁵ Pa SF₆, and insulation mineral oil situated with equal inter-electrode gap equal to several millimeters, have approximately equal electric strength. The degrees of influence of basic parameters of the insulation system on electric strength of SF₆ and vacuum are presented. Advantages and faults of vacuum, SF₆, and insulation mineral oil are mentioned, taking into account possible use of these media as a high-voltage insulation in various electric equipment. Mathematical processing of the test results was carried out with the use of the Statistica software [5].
