Abstract
A pole of a high- and/or medium-voltage circuit breaker, including an insulating housing, at least one, interruption chamber which is positioned inside the insulating housing and contains at least a moving contact and at least a fixed contact. A device for measuring the electric current flowing through the pole, and a dielectric gas, the particularity of which is the fact that said device for measuring the electric current flowing through the pole includes an optical current sensor arranged within a volume of the pole that is occupied by the dielectric gas.
