Abstract: A method for controlling a switching device having at least one phase comprising at least one couple of contacts which can be actuated for switching between a closed condition and an open condition, comprising: - providing control means for controlling the actuation of the at least one couple of contacts, such control means being adapted to operate using time cycles; - setting the time cycles with a predetermined time duration; - detecting a difference of a value of a parameter associated to the phase with respect a preset value; - if the value of the parameter is equal to the preset value, controlling the actuation the couple of contacts through the control means using the time cycles with the predetermined time duration, so as the switching of the couple of contacts is controlled to occur at a predetermined electrical angle of a waveform of an electrical signal associated to the phase; - when the difference is detected, modifying the predetermined time duration according to the detected difference; and - controlling the actuation of the couple of contacts through said control means using the time cycles with the modified time duration, wherein the modification is such that the switching of the couple of contacts is controlled to occur at said predetermined electrical angle.

Abstract: The invention relates to a control unit (7) for a medium voltage switching apparatus (1).
The control unit is characterised in that said control unit (7) is adapted to carry out a diagnostic method (100) to check operating conditions of one or more components of said electric poles (2).
The diagnostic method (100) comprises the following steps:
- basing on a selected ideal position curve (C IP ), obtaining (101) one or more first curves (C Iv , C IT ) indicative of an ideal behaviour of said switching apparatus, during an opening manoeuvre or closing manoeuvre of the switching apparatus;
- basing on detection signals (P F , v F , T F ) provided by a closed-loop control arrangement (72) of said control unit, calculating (102) one or more second curves (C Av , C AT ) indicative of an actual behaviour of said switching apparatus, during an opening manoeuvre or closing manoeuvre of said switching apparatus;
- carrying out (103) a comparison procedure (150) among said first and second curves (C Iv , C IT , C Av , C AT ).
