1. A gas monitoring system comprising:
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,
a first sensor connected to the first chamber and a second sensor connected to the second chamber, both sensors adapted to measure a physical property of the insulating gas in their respective chambers over time, and
a computer unit adapted to calculate from the two sensor measurements in the two separated chambers a leakage rate of the insulating gas in one of the two chambers and that an adaptive filter is used for the calculation.
