Power Transformers with Built-in Harmonic Filtering

Harmonic filtering has always been conceived from outside the transformer in the plant or in the building. In recent times it must be possible to allow a continuity of operation of the transformer even when the harmonic limit parameters have been violated. The reality is that every transformer has its own capacitance and it also has coil portions that fall into disuse when the transformer already has its taps or terminals selected. In this case the commutator fulfills the function of giving us this possibility supported by the computational help.
