Quality of the earth pit needs to be checked and enhanced. Check the continuity of the earth bus/ conductor, check for improper joints in the earth bus / conductor and correct it. Earth resistance will reduce and the voltage difference between neutral and earth will also reduce.
Check also for the loose or floating neutral and correct it.
What else can I help you with?
If in the three phase connection phase to phase voltage is 400v what will be the phase neutral voltage?
The formula to use is, phase voltage /1.73 = phase to neutral (ground) voltage.CommentThere is no such thing as a 'phase to phase', or 'phase to neutral' voltage. The correct terms are 'line to line' and 'line to neutral'. So the above answer should read: line voltage/1.73= line to neutral voltage = phase voltage.
Voltage across Neutral and earth for a 3 phase auto transformer?
A grounded neutral will be at earth potential. A floating neutral will be at a voltage dependent upon the voltage imbalance between phases, and the design of the transformer.
Could the neutral point voltage be like phase voltage?
Yes,when the neutral potential is at ground potential i.e., 0v.
What is max neutral voltage?
220
Why neutral ground voltage is 120v sometime 0v?
There should be no voltage on the neutral wire to ground. This is a serious situation. Call a qualified electrician to check this out.

Should there be voltage between the neutral and ground?
No, ideally there should be no voltage between the neutral and ground wires in an electrical system.
What is the voltage of the neutral wire in an electrical circuit?
The voltage of the neutral wire in an electrical circuit is typically close to zero volts.
What voltage does a neutral wire have in an electrical circuit?
In an electrical circuit, the neutral wire typically has a voltage of around 0 volts.
What neutral means in electrical?
Neutral is the return of the voltage not used by the appliance
When phase and neutral will short means what will be the voltage in neutral?
If the phase and neutral wires are shorted together, the voltage in the neutral wire will be the same as the phase voltage. This is because the short circuit effectively bypasses any impedance or resistance in the circuit, causing the potential difference between the phase and neutral wires to be equal.
What is max neutral voltage?
220
What is the voltage level typically found in a neutral wire?
The voltage level typically found in a neutral wire is close to zero volts.
Why no electric shock from neutral line?
There is normally no voltage on the neutral line because the neutral line is grounded. However, and this is always important, do not assume that neutral is grounded, nor that there is not an elevated voltage on neutral or ground due to a possible ground fault.
Why is it that when you touch the neutral in a box that is not connect to the panel cause the test light to come when touching the power wire?
It shouldn't. The open end of a non connected neutral should have the same potential as the voltage feeding the circuit. The only time a voltage will show is when the return neutral is tested with a meter to the neutral bar or the ground return bar. It will then show what the supply voltage to the connected load is. Once this neutral is connected to the neutral bar there will be no voltage shown across the test meter between the neutral and the neutral bar or the ground bar.
