We have one Energy meter for Measuring the
voltage,current,power,energy(KWH,KVARH,KVAH) & power
factor.The problem is that the meter does not show whether
the PF is lagging or leading.So i want to know that is
there any way or calculation to find out that whether the
PF sign (lagging or leading) depending upon the above
mentioned parameters?
