If the potential coil is missing then the meter reading
will not advance i.e. the meter reading will stop
incrementing as the rotation of the energy meter disc is
dependent upon the interaction of fluxes created by the
shunt and series magnet with each other's induced current.
And when the flux created by the potential coil is absent
then the deflecting torque would be zero and hence the
rotating disc will not rotate.

if we convert kw into kva,which one formula use by us,pls tell me?

We say that if voltage in a power system is increased,for a constant power the current will decrease (by P=VI). isn't this in disagreement with the ohms law(I propotional V;resistant const.).Since the resistance of transmission lines remains constant,shouldn't inc in voltage cause inc in current across the transmission line? I have read many articles across the net but still couldn't this figure this out. :( Guyz plz assist me with dis..:)..
