Abstract
This present application concerns a method for preventing an electrical grid from a failure in case of a temporary overvoltage. A method comprising: a) providing an electrical grid line, a surge arrester and a disconnector device with a disconnector unit; b) connecting the surge arrester at one terminal to the electrical grid line; c) connecting the surge arrester at its other terminal to a second terminal of the disconnector device; d) connecting a first terminal of the disconnector device to ground potential; e) interrupting the electrical connection in between the electrical grid line and the ground potential in case of a temporary overvoltage; f) protecting the surge arrester from failure due to a thermal overload caused by the temporary overvoltages by operating the disconnector device before the surge arrester fails due to a thermal overload of the surge arrester.
