can transformer work on dc or not?if we increase the
inductance of transformer can it happen to work on dc?

Answer Posted / r k sharma

No, the transformer can not work on dc as in case of dc
supply,there will be no change of flux linkage with the
secondary winding hence no induced emf in it.Not by
increasing tne inductance.

A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill.
