why DC current not used in Transformer action?
Answer Posted / kk_london
some one said dc does not have flux, dc has flux but it is
constant means the polarity remains same incase of ac the
flux always keeps on changing and produces emf in the same
conductor due to self induction and produces emf in the
other conductor which is placed closely to it due to mutual
induction. It is the principle of transformer

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.
