Abstract
During opening or closing of the apparatus, in particular a circuit breaker while it is electrically isolated, the method consists in: i) recording a signal representative of the variation over time of the pressure inside the interrupter chamber by means of a sensor disposed outside the interrupter chamber and mounted to be in communication with the gas under pressure inside said chamber; ii) recording a signal representative of the variation over time of the position of the moving contact by means of a sensor disposed outside the interrupter chamber and mounted to detect movement of a drive rod; and iii) comparing the above signals with corresponding signals representative of reference operation of the high voltage electrical apparatus for the purpose of monitoring proper operation thereof or of detecting faulty operation of the electrical apparatus, particularly in the event of a valve in the interrupter chamber of the circuit breaker becoming jammed.
