Method for testing capacitive current switching of a circuit breaker

A device for monitoring vacuum quality of a vacuum circuit breaker, the device including at least one rigid assembly including a first stationary conductive surface that is separated by an insulating layer from a second stationary conductive surface that is grounded. The assembly forms a first capacitor having a fixed value, the first stationary conductive surface being arranged opposite an electrically active portion of the vacuum circuit breaker to form, together with the portion, a second capacitor, and an electronic circuit for measuring a variation in voltage of the first capacitor that is representative of a change in state of the vacuum of the circuit breaker.
