Answer / debasis

Resulting neutral current. Generally lighting system has
this type of unbalance. If neutral is not provided then
star point will be shift from its ideal place caused
overvoltage in one or two phase(s).

Answer / ravi teja.a

Resulting flow of neutral current. Generally lighting
system has this type of unbalance. If neutral is not
provided then star point will be shift from its ideal place
to new place with the phase angle related to phase(which
has the higher current value in mentioned phases)caused
over voltage in one or two phase(s).-------is the correct
answer.
