摘要:A method and system for transferring a load (20) from a first AC voltage source(R) to a second AC voltage source (S). A temporary voltage source (T) is connected to theload and the first voltage source via a resistor. The first voltage source is disconnectedfrom the load. The second voltage source is connected to the load. Finally, the
temporary voltage source is disconnected from the load. The temporary voltage sourcemay be independent of the first and second voltage sources, or may obtain voltage fromthe first or second voltage sources. The connecting and disconnecting is done bymechanical switches, by thyristors, or by mechanical switches and thyristors in parallel orin series.
