Whether DC supply given on HV(primary) side, what effect on secondary side .

Question

Accepted Answer

DC supply on HV(primary) side can have various effects on the secondary side.

DC supply on HV(primary) side can cause saturation of the transformer core, leading to increased losses and reduced efficiency.
It can also result in the generation of harmonics, which can affect the performance of connected equipment.
DC supply can cause electrolysis in the insulation material, leading to degradation and potential breakdown.
The presence of DC voltage can also affect the operation of protective devices and control circuits.
Examples of DC supply on HV(primary) side include rectifier circuits, battery backup systems, and power electronics applications.

Accepted Answer

No emf will produce on secondary side as transfomer is itself static part. Secondary side energy transformation with step up or step down voltage with will only be in case of flux cutting , only AC supply required for transformation of electrical energy.
