Answer / er. ankush miglani 9718151073
it is done to make the neutral at zero potential
coz if there is unbalance in potential the neutral may
shift.

Answer / guest
when there is a unbalace among the phases due to change in
load circulating current introduced this fault caurrent can
be eathed via neutral .

Answer / pranjal.job
it is because to make path for the current generated due to imbalance in d three phases

Answer / srinivas@vsp
for stepdown distribution transformers the secondery side ie
lt side y-with nutrel earhto be connected because of load
side the current is not zero ie varying.hence we r connected
y-with nutrel earh......... finally this because of stand by
earth fault in load sideie secondery side..

When batteries are connected in series the voltage increases but the current remains unchanged, how can this be? When you consider ohm's law. i.e. If voltage increases, current increases, providing resistance remains the same.
Dear All kindly let me know that I know about the DG Rating for Example 150 KVA,Now how i will know that how much Ampher load it can offoard.
