WHY HUMMING SOUND OCCURED IN HT TRANSMMISSION LINES?

Answer Posted / subhash tp

The humming sound is coming from transformer
at the time of working is due the magnetic expansion
and de-expansion at the ends of transformer cores.
At the time of working the transfomer core ends are
expanding when supply voltage occures its positive half cycle
and the transformer ends are de-expanding at the time of supply voltage occures its negative half cycle .This expansion &de-expansion is making humming sound,and also this wii continue during the transformer is working.
