摘要： An electric utility sub-station having two transformers which transmit electric energy to customers in different service areas. A throwover is provided which is operative, when a failure occurs in one transformer, to switch the load normally carried by the failed transformer over to the other transformer which then carries the load of both transformers. Operation of the throwover is blocked when the total demand load on both transformers exceeds the capacity of either transformer.
