The scope of this article is to introduce a method to measure the power factor in a 50 Hz alternating current transient. The circuit shall be a R-L type.

Oscilloscopes measure current and voltage and, through the magic of mathematics, calculate power. Unfortunately, power comes in a large number of guises: instantaneous, real, apparent, and reactive.

In this case, we would have a PUE of 1.43. Now imagine you want to use the first method to calculate PUE. If you total all Amps from all racks, and your load power factor is 0.85, you would get 3580 ...

A new calculation for the power rate, relying on new base factors to be applied for the next five years (2018-22), is due to be concluded and announced by early next year.

Reactive power elements such as capacitors and synchronous generators and motors can help overcome issues involving low Power Factor values.
