Abstract: The invention relates to a control unit for a medium voltage switching apparatus. The control unit is adapted to carry out a diagnostic method to check operating conditions of one or more components of said electric poles. The diagnostic method includes the following steps: basing on a selected ideal position curve, obtaining one or more first curves indicative of an ideal behaviour of said switching apparatus, during an opening manoeuvre or closing manoeuvre of the switching apparatus; basing on detection signals provided by a closed-loop control arrangement of said control unit, calculating one or more second curves indicative of an actual behaviour of said switching apparatus, during an opening manoeuvre or closing manoeuvre of said switching apparatus; and carrying out a comparison procedure among said first and second curves.

Abstract: The invention relates to a medium voltage switching apparatus. The medium voltage switching apparatus includes one or more electric poles, each electrically coupleable with a corresponding electric line; for each electric pole, a fixed contact and a movable contact, the movable contact being reversibly movable between a decoupled position from the fixed contact and a coupled position with the fixed contact, the movable contact moving from the decoupled position to the coupled position during an closing manoeuvre of the switching apparatus and moving from the coupled position to the decoupled position during an opening manoeuvre of the switching apparatus; and actuating means adapted to actuate the movable contacts of the one or more electric poles. A control unit is adapted to select and carry out a selectable control routine in response to receiving an input signal at an input arrangement corresponding to the selectable routine.
