Figure 1.11: Distorted Current Waveform
The distortion observed in Figure 1.11 can be modeled as the sum of several
sinusoidal waveforms of frequencies that are multiples of the fundamental 60 Hz
frequency. This modeling is performed by mathematically disassembling the distorted
waveform into a collection of higher frequency waveforms.
These higher frequency waveforms are referred to as harmonics. Figure 1.12 shows
the content of the harmonic frequencies that make up the distortion portion of the
waveform in Figure 1.11.
