Power Factor Calculator
The presented calculation is conducted using the basic formula PF=P/S, where P - watts, S=V×I - volt-amperes. Having said that, a 3-PH circuit demands an added clarification.
Typically, we must add together "P" and "S" values coming from all phases, where SPH=VPH×IPH.
Precisely what needlessly complicate things is the fact that Wye setup is normally seen by its line-to-line voltage, which can be VL-L= √3×VPH.
Alternatively, with regard to delta we normally recognize line current, that is ILINE=√3×Iph.
Thankfully, for well balanced loads in either cases the whole apparent power could be referred to by the very same equation: S=3×Vph×Iph=√3×VL-L×IL .
For that reason in order to avoid misunderstandings and to work with a well-known technique, for 3ph configuration our software employs line voltages and currents: that is certainly what you must enter into specific fields (boxes) pertaining to RMS volts and amps.
