Can a cosine exceed 1.0 (rhetorical question)?

It is invariably lagging, though a value of 1.3 is just silly.

Power factor is the ratio of real power to the apparent power. If it exceeds 1 the real power will become greater than the apparent power its an abnormal condition in general practice......however some cases......http://www.cumminspower.com/www/literature/technicalpapers/PT-6001-ImpactofPowerFactorLoads-en.pdf

Dear mandi,

....abnormal condition in general practice......however some cases......

This implies that in some cases the PF can be > 1 ??? Do you mean that ??? i am sure i must have misunderstood you....

You've got your meter set for the wrong hemisphere. Somewhere, there's a switch marked "N" and "S". Change it to the other position and the meter will read correctly.

If its a digital meter, Its Faulty...get it replaced.

If it an analog meter, you have the wrong meter in place, PF meters are marked Lead\Lag with 1 being the centre point...so get it replaced.

Regards,
Sapper
