What is crest factor and why is it important?

Written on February 9, 2015 at 12:10 pm, by

The crest factor of an AC current waveform is the ratio of waveform’s peak value to its rms value: crest factor = |peak current| / rms current The crest factor for a sinusoidal current waveform is 1.414 since the peak value of a true sinusoid is 1.414 times the rms value. Current waveforms for purely […]
