摘要

It is not often Dominion has to battle a structure fire caused by an improper switch operation, but it happened in the fall of 2010. The results of this event, and the potential for similar events to occur, prompted Dominion transmission engineers to reevaluate their transmission switch application and design. The questionable guyed H-frame switch structure was a design used extensively on the Dominion system and, therefore, raised a great concern for public safety as well as operational reliability of the transmission grid.
