Question

the current will be ____ which is passing through the neutral wire, in case of balance load (minimum, infinity, maximum,zero)​

Answer 1

Answer:

zero

Explanation:

The output of the current transformer, under normal conditions, should be zero - as the current flow in the hot and neutral wires should be exactly the same.

Answer 2

The current will be ZERO which is passing through the neutral wire, in case of balance load.

Explanation:

• A neutral wire is strictly speaking merely a reference wire for measuring the voltage of a live wire, but if it is shared with three or four live wires that are phased such that the total voltage is zero, then the neutral wire will have no current.
• Non-linear loads generate harmonics, some of which accumulate on the neutral. Because there is no potential difference between the two ends of neutral, or because the voltage at both ends is the same, no current flow is detected.
