Answer Posted / sandeep kumar sirka
actually it is related to form factor which is outcome of
rms to avg. value of alternating current.The value of form
factor is 1.1 . We use multiple of 11 in transmission
because of better efficiency in transmission voltage and
decreased flux leakage and less losses occurs in this
multiple 11 or form factor value that's why we use 11kv or
33kv or 66kv as a transmission voltage. And by no other
means the voltage is taken . Every thing depends on
efficiency and low cost transmission and minimum losses.

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.
