What cause current on the neutral line in a three phase?
Current on neutral in a multi phase system is caused by imbalance between the phases. Question: Are you talking about neutral or ground? The two are very different. Although neutral is grounded, it is expected to be a current carrying conductor, so current on neutral is normal, so to speak. Ground, on the other hand is a protective circuit that is not supposed to have any current on it at all.
What happens if there is no neutral in smps circuit?
No neutral means no current and it doesn't work.
Is there a current in star connected transformer in neutral side?
For a perfectly balanced load, with identical loads connected between each line conductor and the neutral conductor, there should be no neutral current. This is because the vector sum of three identical current, displaced by 120o, is zero.However, for an unbalanced load, there will always be a neutral current because the vector sum of the currents will not cancell.
When the neutral switch is open where do the line current flow to?
There is never a switch installed in a neutral line.
What is encountered by the electric current in order to overcome resistance?
heat
What is combated?
overcome or pass
What will happen without a neutral wire?
Current needs a return path to earth to flow. The neutral carries this flow. Therefore, no neutral and no current flow.
Difference between ground and neutral?
As i know,neutral is the return path of current & ground is for any leakage current

What happens if you wire a ground and neutral wire together in an outlet box?
If there is a GFCI in the circuit it will stop working correctly. They compare ground current to neutral current to detect a fault. It makes ground current equal to neutral current which is a fault condition.
How do you find neutral current in star connected circuit?
if it is balanced then neutral current is zero (!,e iR=iY=iB).AnswerFor both a balanced and an unbalanced load, the neutral current will be the phasor sum of the line currents.
What is the limit or range of the neutral current in an unbalanced three phase system for it to be regarded as faulty?
The limit or range of the neutral current in an unbalanced three phase system is the third harmonic in single phase non-linear load current is the major contributor to neutral current.
What happens if there is no neutral in smps circuit?
No neutral means no current and it doesn't work.
Why the neutral cable takes high current than the phase lines in three phase installation?
In a properly balanced three phase system, there is negligible current on neutral. If there is substantial current on neutral, then the system is not balanced and/or something is wrong.
Why neutral cross section is half the phase in three phase cable while it has to carry current of summation of all phase..?
The current carried by the neutral of a three phase four wire system is the un balanced current. If the three phase system was completely balanced on all three phases there would be no need for a neutral, eg a three phase motor. This neutral current will be less that the phase current so a reduction in the neutral size is allowed.
What is the reading ground to neutral?
Ideally ground and neutral should be at the same potential, but as there is current in the neutral wire and no current (normally) in the ground wire there can be a difference. I have personally measured over 25 VAC on the neutral relative to ground in some systems.
