A method for operating an electrical power supply network is described. The power supply network has several levels (N1, ..., N7) of different voltages. The levels are interconnected by switches (S, S1, S2). A first switch (S1) is made so that the maximum interruptible short-circuit current of the first switch (S1) is smaller than the maximum flowing short-circuit current. In the event of failure, a test is made as to whether the short-circuit current presently flowing through the first switch (S1) is smaller than the maximum interruptible short-circuit current. The first switch (S1) will remain closed if this is not the case, and the first switch (S1) will be opened if this is the case. |
