<p>The invention relates to a method of monitoring a gaseous insulation compartment of a high voltage installation characterized in that it comprises the steps of: Measurement (E10) of a current in the installation and of a pressure in the compartment at a given frequency Search (E11 E12) for a change of amplitude of current and when a change is detected: Determination (E13) of a slope associated with a curve of the pressure measurements performed simultaneously with the change of amplitude Comparison (E14 E15) of the slope with a reference value and when the difference between the two is greater than a predetermined threshold Creation (E16) of an alarm of abnormal operation in the compartment.</p> |
