Abstract
A process for detecting degradation of a switching device including: a mobile electrical contact; a control mechanism including: a driving element of the mobile contact, an elastic member linked to the driving element, and an unlocking member configured to release the elastic member so as to move the contact so as to open an electrical circuit; and an actuator configured to displace the unlocking member. The process includes: (i) commanding the actuator, (ii) determining the duration of time between a first instant corresponding to a predetermined position of the unlocking member and a second instant corresponding to a predetermined position of the driving member, (v) carrying out a set of successive commands of the actuator, so as to obtain a set of values of the duration of time, and (vi) determining a degradation of the unlocking member of the switching device from the evolution of the values of the set of values.
