To connect the three-phase transformer only. In the upcoming kakhuen Yy0 harmonic voltage phase but will not result in voltage between the wires.The effect of Dy 11 will not be lost on harmonic voltage phase and voltage between the wires.
The single-phase transformers to third in the series Yy0 to a more harmonic voltage phase. But will not the line voltage is Dy11. Are not the result of harmonics in the phase voltage and line voltage.
The single phase transformer 3. In the model will be more Yy0 harmonic voltage phase. But will not be pressure during the late a Dy11. No effect of harmonics, both in phase and voltage voltage between the late .
