If you are reading a voltage it is the drop across the resistance to ground. To get rid of the voltage get the resistance lower. This can be accomplished by installing more ground rods to the grounding system. Utility companies usually like 3 ohms to ground or less.

∙ 11y agoby perfect earth and neutral , we can reduce the E-N voltage.
<<>>
To reduce ground neutral voltage increase the number of ground rods or ground plates. By doing this the resistance is lowered.
not only the ground plat in consumer side , also do the perfect earthing in transformer neutral . other vise P-N V < P-E V .

∙ 10y agoThe neutral and earth voltages will be equal when no current is drawn from the supply.
The neutral is earthed at the supply transformer, so it may have a small voltage to earth equal to the voltage drop in the neutral wire from the transformer to where the measurement is made.

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.
What is the problem if I measure voltage on an 120vac outlet 96 volts from neutral to ground?
Firstly measure the voltage between your live and earth.Assuming you get ~120 volts here, the problem is a loose neutral somewhere along the line.If you get 24volts the problem is a bad earth connection, with a fault voltage on it.TBH it's most likely the former, as the latter implies 2 separate faults.
How many volts does a brown wire carry?
The three colours used in the UK are: blue (live), brown (neutral), yellow and green stripes (earth). The standard UK domestic voltage is 240 volts.
There is only 20 volts not 120 volts on outlet that was fine the day before.?
This is strange, check the scale on your meter that you are reading, to make sure that you are on the correct voltage scale. If the reading is correct the suggestion would be to get an electrician to look into why there is such a voltage drop on the outlet. Don't read the voltage across the device, read the voltage from the "hot" wire to ground. That should be 120 volts. If you get that reading then there is a problem with the neutral. It could be loose or have a high resistive condition.
How many volts is low voltage?
Low voltage by definition means any voltage from 31 to 750 volts inclusive.
What is voltage between earth and line?
In a typical residential situation there is 220 to 240 volts between the two hot wires that are typically red and black and 110 to 120 volts between neutral and either black or red. The voltage between neutral and earth should be zero.
What to do when there is voltage at neutral?
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 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.
How do you reduce 12 volts to 3.7 volts?
If the voltage is AC a transformer can be used.
Why voltage at neutral in ckt is zero?
You really should be asking why the potential of neutral is zero. 'Voltage' means 'potential difference' which, by definition, cannot exist at at point. The reason is that the neutral conductor is earthed (grounded), and earth is, by general consent, considered to have a potential of zero volts. In practise, however, there is usually a small voltage drop between the neutral and earth, so it would be more accurate to say that the neutral's potential is close to zero.

What is the voltage between neutral and earth if neutral is broken?
Normally, it is zero.Except in very special cases, the neutral and ground (earth) conductors in a building are tied together at one point in the system, so ideally the voltage difference would be zero. The reason that it might not be zero is there is current flowing in the neutral and, thus, voltage drop in the neutral conductor. Since the ground conductor normally never has current flow (unless there is a fault), there will be a difference in voltage equal to the voltage drop across the neutral conductor, which varies with load (current).It should be 0V , but as per our earth pit maintaining that voltage will be varied even also not exceed 5V.
What should be the primisable voltage between neutral and earth in a three phase system?
It is the line to line voltage divided by 1.73. 600V / 1.73 = 347V 480V / 1.73 = 277V 380V / 1.73 = 220V 208V / 1.73 = 120V
Why neutral have zero voltage?
Your question should read, 'Why does a neutral have zero potential?' 'Voltage' means 'potential difference', and you cannot have a potential difference at a single point. A neutral doesn't necessarily have zero potential although it is connected to earth (ground). This is because the potential of earth isn't literally zero; it's just considered to be zero, in the same way that sea level is considered to be zero in terms of height. Furthermore, there is often a voltage drop between the neutral and earth -in which case, the potential of the neutral can be several volts higher than the potential of earth.
I'm using a 18.5 volts 3.5 amps charger to charge a 12 volts battery I want to reduce voltage to 15 volts and current to about or a little less than 2 amps How to reduce charging current and voltage?
You need a regulator.
If a sine wave has a peak value of 220 volts what is the route means square value?
If the Peak to neutral voltage is 220 volts, the root mean square voltage is 155.6 volts (sqrt(220)).
