Answer / glen

if you see the voltage level between earth and neutral is
approx 2to3v
this is becoz
earth is at potential zero
but neutral is not at exact zero
it is zero volt with respect to phase but is floating with
respect to earth

Answer / saravanan

approx 2to3v

Answer / mark spencer

The neutral is connected to earth at the feeder
transformer. The neutral current (from single phase or
unbalanced loads) flowing through the resistance of the
neutral conductors between your position and the
transformer raises your neutral to earth potential
accordingly.

Answer / nitin pulastya

Voltage difference b/w earth and neutral depends upon supply voltage, load and earth pit connectivity(bcz in all same conditions except clay nature means alklye ness and dryness, the voltage diff. is always different) as i have seen in india as well as in Sudan and zambia.
this is not fixed b/w 2or3 volt.
Bcz if the supply output is open ckt then no voltage will get but as the load increases the voltage b/w earth (if earth pit are perfect) and neutral will increase as the earth potential is zero (fixed).

Answer / mphiremath

earth to neautral voltage should be less than 5 volt..

Answer / nitin pulastya

Voltage difference b/w earth and neutral depends upon the leakage current and that depends upon supply voltage, load and earth pit connectivity(bcz in all same conditions except clay nature means alklye ness and dryness, the voltage diff. is always different) as i have seen in india as well as in Sudan and zambia.
this is not fixed b/w 2or3 volt. But it must be as low as possible by making perfect earth pit.
If the supply output is open ckt(zero leakage current)then no voltage will get but with supply as the load increases the voltage b/w earth and neutral will increase as the earth potential is zero (fixed).
