Three-Phase Systems in Power Applications - Engineering

Q1:

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

D at maximum

ANS:A - zero

It is balanced load so the neutral current is zero. We want proof to let do one thing remove the neutral core and observe the circuit there no different.
