Harmonics in Three Phase Transformers - Meaning ... line currents can be found by subtracting two phases current. For examples, The third harmonic present in the phase magnetising current of three phase transformer is not present in the line current. The third harmonic components are co-phase and hence cancel out in the line.[email protected]
