Apart from connection which of the following is different in star/delta or delta/star compare to delta/delta? Correct Answer Impedance offered to third-harmonic currents in delta is more

Because of one delta connection the same conditions are obtained as in D/D connection except that the impedance offered to the flow of third-harmonic currents in delta is now larger and so are third-harmonic voltages.
