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.
