Power Computations | How to compute power factor and power and impedance when you have harmonics
This video shows how to calculate power, impedance, and power factor when in non-linear systems. When signals are periodic and orthogonal, there is no need to use complicated integration to compute RMS values. This video goes through examples of these calculations. This video also shows how to handle situations when have multiple signals with the same frequency, which one has to combine these signals first. When a system is non-linear, one cannot use the famous equation pf=cos(angle), but rather one should use the general equation: pf=P/S. This video shows how to handle this situation.
