Claim 9:
10. A method for calculating a leakage rate of insulating gas in a gas-insulated switchgear, wherein the gas-insulated switch gear has at least two separated chambers including a first chamber and a second chamber which are filled with an insulating gas surrounding high or medium voltage components, the method comprising:
measuring a first physical property of the insulating gas in the first chamber over time with a first sensor and measuring a second physical property of the insulating gas in the second chamber over time with a second sensor, and
calculating from the two sensor measurements in the two separate chambers a leakage rate of the insulating gas in one of the two chambers and in that an adaptive filter is used for the calculation.
