what is the necessity of neutral in 3 phase system?
Answers were Sorted based on User's Feedback
In most of the 3-ph systems neutral is provided just take care of the unbalanced current. Unbalanced current is nothing but when any of the phase is slightly overloaded or in case of phase failure in balanced currents will produced to carry these currents safely to earth without disturbing the other phases and other connected equipment to the distribution board neutral is generally provided.
and all the neutrals of the db's (Distribution boards) are interconnected and at the transformer this nuetral will solidly grounded.

need of neutral does no exist in case of 3-phase inductive
load while connected to motors, but in case of distribution
transformers or any distribution load for single phase
connection purpose we need a neural.
