Zusammenfassung:	Method for determining a presence of anomalous conditions in a switching apparatus installed in an electric line of an electric power distribution grid characterised in that it comprises a sequence of steps for adjusting a lumped-parameter model describing, for each electric phase, the behaviour of said switching apparatus during the opening manoeuvres of said switching apparatus. The simulation values provided by said lumped-parameter model are used for calculating estimation values indicative of the amounts of arc energy borne by the breaking components of the switching apparatus during the opening manoeuvres of said switching apparatus.
