Method for operating a power plant

Abstract

A contact arm and a method for a disconnect switch, having a profile body and a contact element in electrical contact with the profile body to establish electrical contact with a contact counterpart. The profile body has a first diameter parallel to the contact element. The contact element has a concave surface with a radius of curvature and is arranged on a side directed away from the profile body. The radius of curvature is smaller than the radius of curvature of a circle segment having the first diameter of the profile body. The method includes a contact element of the contact arm establishing electrical and/or mechanical contact with a contact counterpart. A concave surface of the contact element which is directed towards the contact counterpart has a radius of curvature, which is smaller than the radius of curvature of a circle segment having the maximum diameter of the contact element.
