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

Answer / john

Is this a revenue meter from the utility company or a power
quality meter? In the case of a power quality meter, there
should be something letting you know if your PF is in a lead
or lagging. I have an Amprobe DMII Pro and it showes an i
after the PF to indicate lagging, .98i, and a c to indicate
leading, .98c. I have also seen meters with lagging PF -0.98
and leading +0.98. Another simple thing you can do is look
at your VAR, if it is in the negative, your in a lead.
As far as a revenue meter from the utility company is
concerned, call the utility company and ask them.
