To calculate power factor, you need a power quality analyzer or power analyzer that measures both working power (kW) and apparent power (kVA). With this data, you can calculate the ratio of kW/kVA.
To calculate power factor, divide working power (kW) by apparent power (kVA). While 100% efficiency may not be realistic, there are a few things that impact how power factor is improved. Power factor correction capacitors can help improve power factor in certain situations.

Fill factor is a way to compare the maximum power of a module (Imp X Vmp = Pmax) to short circuit current (Isc) and open circuit voltage (Voc). It tells us how square a module's I-V curve is, which relates to the efficiency and performance of the module.
The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation. Use this formula to estimate motor horsepower. Horsepower (hp)= Voltage x Amperage x % EFF x power factor x 1.73/746.
Learn how to diagnose power quality issues in older electrical systems using a Fluke multimeters and oscilloscope.
Problems such as loose connections, blown fuses or failing capacitors can reduce the amount of power correction available and, in extreme cases, even cause a total system failure or a fire. This article describes how to inspect power factor correction capacitors and avoid these problems.
What is power factor and why is it important? Learn how to calculate the power factor formula, each component of the equation, and why it matters.
The power factor is the active over the apparent power. Three-phase resistive loads are straightforward, so we will go straight to inductive loads (which also incorporate a resistive component).
Log power over time; check total kWh, power factor, peak demand, unbalance, and harmonics. Test vibration levels against standards and identify maintenance solutions such as rebalancing.
