You almost got the answer. In DC since frequency is zero the
current flow freely. But the main purpose of using
inductance is to restrict the harmonics. In case of
harmonics there is a frequency element playing a role. since
inductive reactance = 2(pi)fL The inductor offers resistance
to this harmonics and thus reduces the harmonics.

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.
