Answer / shahed

earth to neutral voltage can be due to
1. improper or no earth
2. neutral currents flowing
By proper earthing techniques 1. can be solved.
For 2. the neutral current must be reduced . If possible
the rating of the neutral conductor can be increased therby
reducing IR drop. or an isolation transformer may be used
with it's secondary neutral connected to earth.

Answer / shailendra

By doing proper type of earthing with minimum ristance
value. earthing is to be done accordiing to the type and
moisture content of the soil of that particular area.
ASHLOK type earthing is most popular nowadays.

# 4 is the best & right answer by Shahed as I faced &
resolved this problem with this method only.

Answer / piyush rana

Dear Lalvijaybe,
Just reduce the earth resistance(proper earth connection
should be there).

Answer / vipin nain

1_ try to reduce earth resistance
2. Try to balance the loads in all phases.
3. Earthing should be prper nd connections should be brazed...no corrsion be there between joints....

Answer / gaurav patil

Earth pit resistance should be less than 5ohm hence your earthing found ok.or earth to neutral voltage less than 1V.

Answer / raghav

To reduce NEV or earth resistance use Electrodes type earthing instead of pit earthing...

In Dyn11 power transformer if any one of the 3 phases connected to earth in star connected side then please explain effect of the current flow in delta connected side of transformer.(In this case if one phase is shorted to ground in star connected side then we observe the current flow in two phases only not three phases in delta connected primary side. Please explain why it is so?)
