   In the article the aspects of operating electrical field stresses in SF6 insulation of extra and ultra high voltage equipment are considered. On the base of carried analysis of affect of such factors as electrode area, quality of electrode surface treatment, existence of metal or dielectric particles in the gap, gas pressure on electrical strength - the recommendations on operating electrical stresses choice were given.
