A 400 MVA 230 kV phase shifting transformer (PST) is to be installed in the Nelway Substation of the British Columbia Hydro (B.C. Hydro) transmission network. This will be the first PST in the B.C. Hydro system. The Nelway PST is to mitigate the problems associated with the inadvertent loop-flows through the interconnections between the B.C. Hydro and the Bonneville Power Administration (BPA) systems. Phase shifting transformers for similar purposes are being planned or installed throughout the Western Systems Coordinating Council (WSCC). Due to the design and construction of the PST, a detailed analysis of the switching overvoltages for insulation coordination is required. This analysis employs the application of the electromagnetic transients program (EMTP). The analysis is presented in this paper.
