In a three-phase system, when the loads are perfectly balanced, the neutral current is: A.zero B.one-third of maximum C.two-thirds of maximum

zero, so easy

for balanced system the neutral current must be zero

when the loads are perfectly balanced , that means the three phase sysem is a delta connection, there is no neutral connection in the system, so the neutral current is zero..

Zero, because we we connect all the3 phases in star, to neutralise all the system unbalance to ground,when system is perfectly balanced,then it must be Zero

zero

Zero

A. Zero

It's certainly zero. Be careful perfectly balanced means the voltage between each two phases reads the same and the drawn currents are the same.

A.zero

when the loads are balance it is zero

OPTION A IS THE CORRECT ANSWER. THE CURRENT IN NEUSTRAL SHALL BE ZERO IN CASE OF PERFACTLY BALANCE 3 PHASE SYSTEM.
