Neutral is nothing but a point which doesnt have any
potential at all ie) 0V. We know in AC voltage varies from
+V to -V. To create a potential difference which obviously
make a current flow, neutral is used. In otherwords to form
a closed circuit neutral is used which absorbs the
electrons from a high potential region. With out neutral
aclosed circiut cannot be formed in onne phase.

Answer / shipra

Neutral is a lead which connected to the star point of the
system. Whenthere is a three phase imbalance occure its
gives path for in-balance current.

Neutral is a lead which connected to the star point of the

gives path for in-balance current.
And also nutral is a return conductor which is connected
to ground in generating station

Answer / krr

neutral is used for safety......when there is a earth fault
occurs by connecting the device in neutral we can sense the
fault. Also to avoid multiple ground faults.To avoid arcing
ground in which if there is a fault between phase to earth
arc is produced due to which current flowing to ground is
very low, overcurrent can not operate on this small current
hence connecting the device in the neutral we can avoind
the high arcing grounds.For core balancing also neutral is
used.

Answer / dpk_1fj

In a single phase neutral is carrying return current to the
supply and three phase it carry unbalanced current to the
supply.

Answer / praveen kumar

neutral is a return conductor without this return
conductor we cannot closed the circuit

Answer / ravi

Neutral is nothing but non potential wire used to close the
loop

Answer / sikaram

In order to protect the insulators from line voltage while unbalanced faults are occurred.

Answer / prashant

neutral wire is there to pass zero sequence current during
fault condition

Answer / satya

neutral is a non potential wire , it creates a potential
difference to flow the current in the circuit
