Bonneville Power Administration (BPA) proposes to increase the physical distance that separates each phase of the 500/230-kiloVolt transformer banks at BPA’s Lane Substation. The reason for the increased distance is to minimize the effects of a transformer fire or explosion as outlined in the Institute of Electrical and Electronic Engineers, Inc. guidelines for substation fire suppression.
