Patent number: 11726538Abstract: A method and a device are for power supply switchover in a power system, including two power supplies, each being connected to a bus through an incoming line. The power supply currently in operation is used as the main power supply and the other power supply is used as a backup power supply. Both the incoming line and the bus have three phases, and the lines are connected by their phases. In an embodiment, the method includes: determining whether there is at least one sound phase among the three phases after identifying a fault in the power system; and if there is, obtaining a power data on the sound phase before the main power supply is disconnected.
