Why there is a current in neutral line..

If the power system dont have balanced load distribution
between the phases(R,Y,B),The neutral line will get flow of
current. The load distribution(R=Y=B)for the Phases should be
equal
then only the power quality will be high and the Neutral
current will be 0 too...

Why there is a current in neutral line..

Answer / sanjana singh

The neutral wire is connected to ground at the distribution box. When current flows in the circuit, there actually is a voltage drop across the neutral wire, but the wire's resistance is so small that the voltage drop is also very small. So, at the device that's drawing the current, the voltage on the neutral wire is small but not zero. At the distribution box, the voltage is zero.
