1. A redundant power supply comprising the following:
a first power supply, which is connectable to a busbar by a first tie switch and is disconnectably connected to a first load by a first line system;
a second power supply, which is connectable to the busbar by a second tie switch and is disconnectably connected to the first load by a second line system;
a third power supply, which is connectable to the busbar by a third tie switch and is disconnectably connected to a second load by a third line system;
a fourth power supply, which is connectable to the busbar by a fourth tie switch and is disconnectably connected to the second load by a fourth line system;
wherein all of the tie switches are open during normal operation of the power supplies and the loads;
wherein a disturbance is detected on a power supply and/or a line system when a determined current differs from a target value for normal operation and/or when a fault current exceeds a threshold for normal operation; and
wherein, when the disturbance is detected, the redundant power supply is configured to interrupt normal operation and close one or more of the tie switches so that each of the loads is then connected to three functioning power supplies and/or three functioning line systems.
