Question

Why is the magnetising current waveform distorted?

Answer 1

Answer:

Direct current (DC) flowing through the earthed neutrals of transformer windings causes a DC component in the magnetising current. Owing to non-linearity, the waveform of this current is strongly distorted.

Answer 2

Answer:

the material used for the transformer's magnetic circuit is steel.

compared to air steel Has a high magnetic permeability . this helps in reducing leakage flux and also the magnetising current.

but steel also suffers from saturation because of this , the flux density is not directly protional to the magnetising current. as the magnetising current increases, the increase in flux density tapers down.

the applied and induced voltages are sinusoidal .therefore the flux density should also be sinusoidal .
