    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 environment. Depending on the operating duration SF 6 must therefore be checked and replaced regularly.
