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.

∙ 10y ago- zero volts on neutral is ideal but impossible to achieve in practice when the line is in use
- voltages up to perhaps 2 volts on neutral are common and not usually a problem
- voltages up to about 20 volts on neutral can be tolerated but suggest poor connection between the neutral wire and ground, this should be investigated and repaired
- voltages higher than about 20 volts on the neutral are a severe problem and possibly a fire hazard, the circuit should be taken out of service immediately and repaired

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.

What neutral means in electrical?
Neutral is the return of the voltage not used by the appliance
What is max neutral voltage?
220
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.
Does a neutral white wire have voltage?
yes

There should be no voltage on the neutral wire to ground. This is a serious situation. Call a qualified electrician to check this out.
What is the total of a phase to earth voltage on 11000 volts?
An 11,000 volt three-phase supply has a voltage of 6351 from live to neutral, when there is a neutral wire.
Could a neutral wire be powered?
There should be zero voltage between neutral and ground.
What voltage should 208 3 phase leads read?
From line-to-line (any two of the three leads) voltage or 'line voltage', the voltage is 208 V. The line-to-neutral (one of the three leads and the neutral conductor), or 'phase voltage', is 120 V.
