138-kV six-phase Charleroi-Yukon Line uprating study for Allegheny Power Service Corporation

Technical Report ·
OSTI ID:6887912
Results of a one-year study of the terminal equipment design and costs for two transmission alternatives for uprating Allegheny Power Service Corporation's 138-kV Charleroi-Yukon Line are presented. The two transmission line uprating alternatives were (1) a 138-kV six-phase line, and (2) a 230-kV three-phase double-circuit line of comparable power transfer capability. Transformers, circuit breakers, arresters, relay protection equipment, and transmission line voltage uprating requirements were investigated. Preliminary designs were developed for new equipment suitable for 138-kV six-phase operation. The line termination equipment designs and costs for the two transmission uprating alternatives presented in this report may be used with other Allegheny Power Service Corporation studies to evaluate their effectiveness as viable transmission system elements in future APS system designs.
