Get What Is The Crest Factor And Why Is It Used

Crest factor is a parameter of a waveform, such as alternating current or sound, showing the ratio of peak values to the effective value. In other words, crest factor indicates how extreme the peaks are in a waveform.

The crest factor is the ratio of wave height, which is one of the quality parameters in Alternating Current (AC) power sources and Bipolar power supplies. In the field of electronics, it is used to describe the state of the AC power source supplied from an outlet.

At half scale, the crest factor is double, or 6.0. For example, some meters will have a crest factor specification of 3.0 when measuring 300VAC and 6.0 when measuring 150VAC. Wattmeter accuracy is also susceptible.

The definition of Crest Factor is: true peak value of time waveform / rms value of time waveform. At the beginning stage of bearing damage, the bearing's inner race, outter race, rolling elements and the cage may. generate periodical spike signals (numerator). That would cause the Crest Factor value to increase.

The crest factor is the ratio between the value of the peak current or voltage(IM or UM) and its r.m.s. value. . It is generally between 1.5 and 2 and can even reach 5 in critical cases. A high crest factor signals high current peaks which, when detected by protection devices, can cause nuisance tripping.

The definition of Crest Factor is: true peak value of time waveform / rms value of time waveform. At the beginning stage of bearing damage, the bearing's inner race, outter race, rolling elements and the cage may. generate periodical spike signals (numerator). That would cause the Crest Factor value to increase.

By comparing the difference between peak and average levels, crest factor measurements give us a very good way to judge the balance between transient and sustained elements in a mix, and provide an indication of how to approach compression and limiting treatment.
