Design of High Voltage Transformer Windings Withstanding Surge Voltages

open access: yesIEEJ Transactions on Power and Energy, 1999
High voltage windings of high power transformers, have to be designed in such a way as to withstand surge voltages. From this point of view, interleaved windings have the better behaviour, but they are much more expensive with respect to continuous ones.
