The neutarl to earth voltage in system is 7volts on
Electricity power but it lowers to 1.3volts when load
transfered to DG power.what may be the reason.

Answer Posted / vitthal upare

Its depends upon healthyness of earthing and nuetral. for
good earthing there should be minimum voltage drop between
earth and nuetral.
So from above example its clear that neutral or earthing of
Transformer not proper. It can be check by earth tester

1 “earthing” for bonding of equipment and circuits to common plant earth electrode potential, 2 “protective earthing (PE)” when this bonding is required for personal safety provisions 3 “grounding” for interference suppressing bonding of screens, sys-tems with ground level 4. low-impedance earthing ? 5.primary earthing system and secondary earthing system what is that? 6.earthing electrode or mesh net earthing electrode ? very confusing , simple but very informative help required ? i will be very very thankful to you guys.
