Abstract
A monitoring device for switching systems including a contact assembly having at least a movable contact and a kinematic chain for actuating said movable contact and opening/closing the contact assembly. The monitoring device includes: an accelerometer adapted to be positioned on a moving part of the switching system and capable of determining acceleration data of the moving part; a control unit including: a first processing unit adapted to receive acceleration data measured by the accelerometer and calculate timing instants of predetermined events and motion parameters related to the switching system; a second processing unit adapted to receive the timing instants of predetermined events and the motion parameters and to use at least one timing instant and at least one motion parameter to calculate electro/mechanical parameters of the switching system.
