WHY DOES NEUTRAL DO NOT CARRY EVEN THOUGH IT CARRIES RETURN
CURRENT?
Answer Posted / pratheesh
In three phase system, if the loads on all three phases are
equal, there will not be any current flow through neutral.
Remember the star point of motor. I1+I2+I3=0. If there is
no potantial in neutral with respect to ground, there will
not be any current flow.
But if the loads on any phase/s are not equal to others,
I1+I2+I3 is not equal to 0. So in this case there will be
some potential on neutral wire at the load side and this
will creat a current flow to the star point of trasformer.

L.A. (Lightening Arrester) is located at a place from where transmission line enters the transmitting substation. So L.A. (Lightening Arrester) is the first equipments which has to encounter with lightening, high voltage surges and switching surges. It has to absorb energy of lightening, high voltage surges, and switching surges. L.A. (Lightening Arrester) is made up of layers of semiconductors. If these layers can not tolerate energy released by lightening, high voltage surges, and switching surges the L.A. (Lightening Arrester) blasts.
