Interruption of capacitive currents
The interruption of capacitive currents is a usual switching case, unlike the making and breaking of fault currents. The usual cases, in which a capacitive current is switched, are switching of unloaded overhead transmission lines, local substation components, cables, capacitor banks and others.

First, let’s explain the basic nature of these cases in which a capacitive current is switched and then in details 1-phase and 3-phase cases.
