The particularity of phase shifting transformer and the specific focus issues during design process are presented
including the technical data of a practical transformer
the design principle of single-core phase shifting transformer
the selection of on-load tap changer & the winding arrangement in the phase shifting transformer
the phase-shifting angle and impedance calculation method
as well as the potential shielding that are set between the windings to reduce recovery voltage.This will offer experience and references for designers for similar transformers in future.
