Answer Posted / alok ranjan
when dc supply is given to the transformer momentary emf will be generated at the secondary side and will collapse suddenly.
because flux does not change periodically due to dc supply.it changes only when it is switched from off to on or on to off.
primary coil may burn but Burning or not burning of primary depends on design consideration whether it can carry current according to applied voltage or not.because for dc,inductance will be zero so resistance of primary will be less than ac impedance, so current and I^2R loss will increase may cause to burn.

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.
