Electrical Energy Supply Facility for Electrically Coupling to a Multiphase Electrical Energy Supply Network

A method for producing an electrical energy supply facility for electrical coupling to a multiphase electrical energy supply network. The method includes providing a multiphase inductive or capacitive load unit with a number of load terminals corresponding to a number of phases of the energy supply network, wherein each of the load terminals is electrically coupled to a respective phase of the electrical energy supply network; capturing respective electrical phase currents of the load terminals using at least one current sensor; evaluating the phase currents; establishing a residual current; and establishing the phase of the electrical energy supply network with a smallest or a largest phase current, wherein this established phase is electrically coupled to an electrical reactor, a reactance value of which is established dependent upon the residual current established.
