Abstract
The disclosure relates to a standby power supply system for connection to a superordinate power supply network and a local power distribution network, having a network isolation device for connecting the local power distribution network to the superordinate power supply network by means of at least two series-connected switching elements with respectively associated switching contacts and having a local power supply device with a separate-network detector for identifying a separation situation for the local power distribution network. A first of the two switching elements is connected to the superordinate power supply network and the second of the two switching elements is connected to the local power supply device. The disclosure furthermore relates to methods for isolating a local power distribution network from a superordinate power supply network.
