Answer Posted / surendhar
All electrical Circuits have ground point (the reference
point). It may be earth grounding (where reference point
connected to earth) or Chasis grounding (reference point
connected to chasis as in aircraft, car etc) or Floating
ground(where the reference point is not connected
anywhere).
Earthing, where the equipment case is connected to the
earth, to protect the equipment and the people who come in
contact with faulty conditions (Metal case of the equipment
coming in contact with the line).
If neutral is not present (floating neutral), then there
would be significant rise in the voltage at the neutral
point in the star connection (at the load end), because of
unbalancement in all three phases (practical case). This in
turn would affect the equipments connected across each
phase. So Neutral wire connects the neutral point at the
load end and the transformer end, where it would be
grounded. This causes current to flow in the neutral under
unbalanced situation, back to the transfomer, negating the
rise in voltage @ neutral point in load end.

How do i perform grounding of star point of Genset (400V) for making connection with step up transformer of DELTA-DELTA (400V to 20KV) ? while Genset itself has its own neutral and grounding bus bar inside genset breaker box whereas we have another neutral and grounding busbar in synchronizing panel next to genset at maximum distance of 6meter, would someone pls advice if we can only perform neutral grounding in synchronizing panel or should we ground neutral on both places inside genset breaker box and synchronizing panel.
