Answer Posted / shah alam
the HT lines causes humming because of corna effect.when
the voltage of transmission lines increases too much to
produce electric field of magnitude of 10^7 v/m.That is
more than the electric field required to break the
intermolecular bond of the air molecules.Hence the air
particle around the lines get ionised and start moving
freely.and during this movement several collisions occur
and resulting a humming sound.
