the answer to this question is that electronic meter
possess a microprocessor which is interfaced by a
Programmable Periphral Device which receives its Input from
Two CT's, one is on the phase & the other is on the
neutral,the PPI recieves signals from both CT,s but it
reads whichever the current is greater & a V.T. is
positioned in the casing of Energy meter of which outputs
is fed to PPI so the proceessor reads V from V.T.,I(depends
on Power Factor) from C.T. so their product is seen on the
digital screen of the Meter.

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.
