Voltage Between Neutral And Earth. Turned power off to change a socket front. And earthing voltage suppose 2 volt.
What is difference between Ground and Neutral? Quora from www.quora.com
Depending on the current, length and resistance of the neutral conductor, the neutral to earth voltage can be up to 10v. In an ideal ac system, neutral and earth should be at the same potential, which means the voltage measured between the neutral and the earth should be zero. If neutral is perfectly earthed line to neutral voltage is always seems to be same.
The Multimeter Was On 2Vac Range And Attached To The Adjacent Socket Neutral And Earth As Shown In Your Question.
It’s measured between the neutral (white) conductor and safety ground (green or conduit) conductor of the electrical system. Turned power off to change a socket front. Earth or ground an earth or ground is a safety connection to protect personnel from electric shock.
If It Is A Joint Earth It May Go To 1 To 2 Volt.
The neutral back at the star point of the 3 phase & neutral distribution transformer is connected to earth, the 3 phases, neutral and earth are then brought to your incomer,you should have 400 v between phases and 230 v between each phase & neutral and between each phase and earth, there should be no or little voltage between neutral end earth in a healthy system as. Poor earth connection at local earth point. Voltage between them (v) live and neutral:
Mathematically You Can Find Line (Phase) To Neutral Voltage From Line To Line (Phase To Phase) Using Below Equation.
The voltage drop between the live and neutral, and live and earth will both be 230v, but the voltage drop between the neutral and earth. Causes of high voltage between earth to neutral. If neutral is perfectly earthed line to neutral voltage is always seems to be same.

From the above, it would seem that any voltage above 25 volts can be seen as a fault. Reg 8.6.6 states that if the voltage between neutral and earth exceeds 25 volts, then the supplier must be notified. And also between phase r and earth its 380 v, y and earth is 380 v, while blue phase and earth is 34 v.
Poor Earth Connection At The Substation.
Now, that we have a brief idea what earth and a neutral is, let us look into their differences. If that were the residential voltage, you should expect neutral may reach 5% of line voltage by design. Regarding the phase and neutral is 220 for all phases.
