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.

A powerplant has 8 gensets operating in grid parallel mode. In one genset sometimes there is pf variation and kvar variation. The plant operates in pf mode. When this variation is observed the load is stable, voltage is also stable, freq and genset speed is also stable. How will you check the functioning of pf card.
