Abstract
An electrical network includes feed-in means, loads, and a distribution network located therebetween which includes at least one dynamic isolator and busbars. The feed-in means and the loads together with associated busbars are disposed in groups which can be electrically interconnected or disconnected by the at least one dynamic isolator. The at least one dynamic isolator monitors the voltage on the busbars adjacent thereto for a voltage difference. In a normal state without a voltage difference, the at least one dynamic isolator electrically disconnects the groups from one another, and in the event of a voltage difference between the busbars adjacent thereto, the at least one dynamic isolator electrically connects the groups to one another.
