How is Power Factor Measured?
Power Factor, no matter where it is measured, is simply the relationship between the True Power that is being delivered to the facility and the Apparent Power, which is the actual power that is being consumed by the equipment and is measured by a meter that can differentiate that relationship. The utility measures power factor as a ratio of the true power measured by the wattmeter, versus the apparent power which is a function of the Voltage and Amperage.
