Abstract

1. A device for limiting earth leakage currents in a three-phase supply network with a compensator connected between a neutral point in the network and earth, said compensator generating in case of an earth fault a complementary current adjustable independently of amplitude and phase position for compensation of the reactive and active components of the earth leakage current, characterized in that the compensator consists of two controllable three-phase transformers fed on their primary sides by a separate three-phase current source.
