Power Factor info
(OP)
I must investigate about power factors and I do not know anything about them. Could someone give me a basic explanation about the causes and defintions and all things relevent to a power factor. Also I am looking of info on voltage disrtotions and power distortions casued my high voltage lasers. Or links to helpful site would be appreciated.

PF=Pwatts/Sva=Pwatts/(Pwatts**2 + Qvars**2)**0.5
If the current and or voltage waveform(s) are/is distorted by harmonics, then more complex equation(s) for the power factor shall be used.

...well, you get the idea

In the presence of sinusoidal voltage supply (a helpful approximatio), Overall PF can be expressed as the product of a displacement power factor (cosine of displacement angle between the fundamental voltage and current) and a distortion power factor (distorion power factor is the ratio of the rms quantities I1/Itot where Itot is rms of total current waveform including fundamental and harmonics)
