Abstract
A method for the transferring of 3 phase, asynchronous AC power between a present source supplying power to a load and an alternative source to supply power to the load. The maximum phase displacement is 60 electrical degrees at the load. The transfer can occur between sources which are rotating "forward" or "backward" with respect to each other or jointly with respect to the load. Either present source, alternate source or the load may be used as the timing reference for determining best phase connection of the alternate source to the load.
