Abstract
A method for determining an operational status of a switching device for switching an electrical unit including a first circuit and a second circuit, each circuit respectively including: a vacuum breaker including a fixed electrode and a mobile electrode; and a control device connected to the mobile electrode via an elastic device. The method including: for each of the first and second circuits, determining a transition instant at which the mobile electrode comes into contact with the fixed electrode; determining a difference between the transition instant of the first vacuum breaker and the transition instant of the second vacuum breaker; determining that the operational status is a first status known as “nominal synchronization” if the difference is less than a threshold; and determining that the operational status is a second status known as “abnormal synchronization” if the difference is greater than the threshold.
