.PowerSystems.AC3ph.ImpedancesYD.Partials.ImpedYDNonSymBase .PowerSystems.AC3ph.ImpedancesYD.Partials.ImpedYDNonSymBaseSame as ImpedYDBase, but contains additionally a Park-transform which is needed for transformation of general impedance matrices from abc rest to general dq0-system. (for example when coefficients of non symmetric systems are defined in abc representation.)
