Abstract
An electric plant with a safety device, a method for remedying faults in a switchgear installation, and the use of a closing contact to provide security against faults. The plant includes a switchgear installation, consumer loads connected to the switchgear installation, and at least one feeder cable to the switchgear installation. The plant provides a strong consumer network that still has a high degree of safety against damage caused by short-circuiting faults. The plant includes at least two feeder cables, each connected to its own current source such as a transformer or a generator. At least one of the feeder cables is connected by a branch cable to ground. The branch cable is provided with a closing contact, which is normally open. The closing contact is arranged to be activated, i.e. to quickly close the connection to ground, in the event of short-circuiting in the switchgear installation.
