Surge means sudden increament. In electrical ckts, due to
some internal & external faults. sometimes the fault may
induce the overcurrent or overvoltage. to protect the
system from this spikes, we use the surge arresters.

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.
if in 3-phase system voltage=440V,frequency=60Hz, current=400A. then if it is single phase then current=? and if it is single phasing then current=?
