Reducing transient activity increases this efficiency and will, therefore, increase power factor…to which the next logical question is “How much?”
The amount is related to the amount of transient activity that is present to interact with this magnetic field. It cannot be estimated. If it is assumed that transient activity can produce up to a 10% loss in efficiency related to hysteresis losses, and the reactive loading of motors ranges between 20% and 60%, it could be inferred that it will increase power factor by a relatively small amount….2% to 6%. What confuses many people is that this “2% to 6%” is only of the difference between the actual power factor and the theoretical “perfect” power factor of 1.0. If you have a power factor of .86 and increase power factor by 6%, you’ve only gone from .86 to .87 (6% times the remaining 14% of power factor available is only 1 percent) The difference in our installation is that we distribute our equipment throughout your facility putting it closest to the equipment being measured. Most power factor correction is done at the service entrance…to make the utility happy.
