DIN VDE V 0126-1-1 VDE V 0126-1-1:2013-08

Automatic disconnection device between a generator and the public low-voltage grid

Class/Status: Standard, withdrawn
Released: 2013-08
VDE Art. No.: 0100178

The automatic disconnection device is used as a safety interface between the generator and the public low-voltage distribution net and serves as a substitute for a disconnecting switch accessible at all times by the distributing network operator. It prevents the unintentional supply of electrical energy from the generator into a subnetwork disconnected from the rest of the distribution grid (islanding), thereby offering additional protection to the measures specified in DIN VDE 0105-100 (VDE 0105-100), 6.2 to
- operating staff, against voltage in the disconnected subnetwork
- equipment, against inadmissible voltages and frequencies
- consumers, against inadmissible voltages and frequencies
- equipment, against the feed of faults by the generator.
