Gas-insulated switchgears are furthermore never absolutely leakproof. Leaks in seals, flanges, etc. allows SF 6 to emerge and allows air to enter. The loss rate of sulphur hexafluoride is generally about 0.5 percent by volume of SF 6 per year. These leaks must be eliminated immediately, since sulphur hexafluoride is extremely harmful to the
