摘要:
An exemplary electrical network in form of a ring system includes a plurality of infeed transformers which are arranged in parallel between a sourcing busbar/cable system and a ring load busbar/cable system. A junction point connects each infeed transformer to the ring load busbar/cable system. The network includes a plurality of current limiters, where each current limiter is positioned between two junction points. Upon a fault event of an infeed transformer, two current limiters on both sides of a respective junction point of the faulted infeed transformer are simultaneously tripped in order to reduce current in the ring load busbar/cable system.
