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.
Current needs a return path to earth to flow. The neutral carries this flow. Therefore, no neutral and no current flow.
As i know,neutral is the return path of current & ground is for any leakage current
Yes, a neutral wire carries 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.
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.
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.
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.
No neutral means no current and it doesn't work.
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.
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.
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.
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.
