Method for operating an electrical switching device within an electrical switchgear system

Abstract

The invention relates to a method for operating an electrical switching device within an electrical switchgear system, by way of which existing disadvantages can be eliminated, and a secure and protected operation of the electrical switching device outside a potential hazard field can be made possible. The electrical switching device is operated by an operator by means of a mobile electrical device, which communicates wirelessly with the electrical switching device. In a first step, the operator reads a first identification means with the use of the mobile electrical device in order to unequivocally identify the electrical switching device to be operated. In a second step, a second identification means is read with the use of the mobile electrical device in order to unequivocally identify a protected operator location. In a third step, the operator is authorized to operate the identified electrical switching device with the use of the mobile electrical device, when the operator is located at the identified operator location.
