Answer Posted / muthukumar
Because of high voltage the air molecules surrounding the HT
line are ionised.As the HT line carries AC current the
alternating magnetic field produced will cause the ionised
molecules to vibrate resulting in humming noise.
You can also consider the case that there will not be any
humming noise in case of HVDC transmission.
