The neutral current in a balanced load condition flows due
to the third harmonics which is basically due to the use of
inverter drives, PLC etc. in the distribution system.

Answer / guest

neutral, in ideal case. but if the current is flowing in
neutral when the load is balanced that means its due to the
effects of harmonics.
