Abstract
A method of predicting a lifetime of a gas filling of an electrical switchgear is disclosed, wherein pressure values p, pin a system of the electrical switchgear containing the gas filling at a predefined temperature Tat different points in time t, tare measured. Based on the pressure difference Δp between the pressure values p, pthe lifetime of the gas filling is calculated. Alternatively, the pressure values p, pcan be taken at temperatures T, Twithin a predefined temperature range at different points in time t, t.
