METHOD FOR COORDINATING PROTECTIVE DEVICES IN A DISTRIBUTION GRID

In a method for coordinating a distribution grid of different levels of electromechanical switches and automatically electrically closable apparatuses in a DC circuit, the distribution grid is arranged between feed-in devices and loads and includes at least one busbar. Each of the apparatuses includes an electrical switch to open or close the DC circuit, a fault current detection device, a tripping unit, and a pre-charging apparatus.
