why the neutral point is zero in star connection?..

Answer / sujeet kumar

well i think it is only zero for a balance load in case of
balance load all current are in 120 deg so resultant is zero
but in case of un balance load it will not be zero

why the neutral point is zero in star connection?..

Answer / anshul kumar goyal

According to KCL
Cuurent coming to the point+current going away from the
point=0
Therotically same rule applies in star connection only if
load is balanced, but practically current at neutral point
is not 0 as .
To make the neutral current 0, earthing is provided in the
transformer commissioned at DT through a bush.
This earthing provides minimum resistance path for the
accessive current.
