.Spot.ACdqo.Shunts.Partials.ShuntBaseNonSym .Spot.ACdqo.Shunts.Partials.ShuntBaseNonSymSame as ShuntBase, but contains additionally a Park-transform which is needed for transformation of general impedance matrices from abc rest- to general dqo-system. (for example when coefficients of non symmetric systems are defined in abc representation.)
