Electrical network in form of a ring system comprising several infeed transformers (T1...Tn) which are parallel arranged one to another between a sourcing busbar / cable system (1) and a ring load busbar / cable system (2), wherein the ring load busbar / cable system (2) comprises several current limiters (A1...An) arranged to both sides of junction points (BB1...BBn) of each infeed transformer (T1...Tn) to the ring load busbar / cable system (2) in order to reduce the current in the ring load busbar / cable system (2) in a fault event, characterized in that, the two current limiters (A3, A1; A1, A2; A2, A3) to both sides of the junction point (BB1; BB2; BB3) of the faulted infeed transformer (T1; T2; T3) are simultaneously tripped in order to reduce the current in the ring load busbar / cable system (2) in a fault event. |
