I think you mean "what is the permissible imbalance between live and neutral current"
All current supplied by the live wire should exit via the neutral. Any imbalance leaving via Earth is detected by an earth leakage circuit breaker . They trip at about 30 mA.
What else can I help you with?
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
Does a neutral wire carry current in an electrical circuit?
Yes, a neutral wire carries current in an electrical circuit.
Does neutral carry current in an electrical circuit?
No, neutral does not carry current in an electrical circuit. It is used as a return path for current to flow back to the source.
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.
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.
Why neutral wire does not carry current in closed ac circuit?
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
What happens if there is no neutral in smps circuit?
No neutral means no current and it doesn't work.
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.
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.
Does the neutral wire carry current in an electrical circuit?
Yes, the neutral wire carries current in an electrical circuit, but it is designed to carry the current back to the power source to complete the circuit.
Why the neutral cable takes high current than the phase lines in three phase installation?
In a balanced three-phase system, the current in the neutral wire should ideally be minimal as the three phase conductors carry equal and opposite currents that cancel out in the neutral wire. However, if the loads are unbalanced, the neutral wire may have higher current due to the uneven distribution of power among the phases. This can happen when loads on each phase are different or when single-phase loads are connected between a phase and neutral, leading to increased neutral current.
