Abstract
A method and system of non-intrusively monitoring the proportion of a component in a gaseous mixture having at least two components and contained in an electrical switchgear enclosure includes measuring the pressure, the temperature, and the density of the gas mixture by using sensors mounted on said enclosure, and in determining said proportion by processing the measured values in a data-processing unit.
