In this chapter, we shall discuss distortion of the line-voltage
sine waves. Distortion to the line-voltage waveforms can be
caused by transient or continuous disturbances. Examples of
transient disturbances include lightning, motor starting and
stopping, clearing faults, and other harmonic-generating
occurrences. Throughout the chapter, we use PSPICE
simulation results to illustrate examples of voltage distortion.
A chart summarizing voltage distortion and its causes is
shown at the end of this chapter.
