Abstract
The subject matter of the present invention is a method of automatically recognizing an electrical system by which both the voltage of an electrical system (2) and the phase angle between phases of the system are monitored so that human technical failure upon connecting a plant (1) to said electrical system (2) be reliably prevented.
Claims6
A method of automatically recognizing an electrical system by which both the voltage of an electrical system (2) and the phase angle between phases of the electrical system (2) and the phase angle between phases of the system are monitored, comprising the steps of:
- providing for the interrupting of the mains electricity supply on the basis of mains electricity supply limit values, upon the reaching of which, the mains electricity supply must be interrupted, and
- automatically recognizing and automatically adapting the voltage and phase measured via voltage and phase measuring means as well as,
- controlling the voltage and phase via control means to the system (2) that is to be supplied with electricity.
