WebK-factor values range from 1 to 50. K-factor of 1 is used for linear loads only, and a K-factor of 50 is used for the harshest harmonic environment possible. A K-factor of 13 is typical. When transformers use a K-factor value, they are said to be K-rated. The use of a K-rated transformer is anywhere non-linear loads are present. WebTotal Harmonic Voltage Distortion or THD, of a signal is a measurement of the harmonic distortion present and is defined as the ratio of the sum of the power of all harmonic components to the power of the fundamental frequency. THD is used to characterize the power quality of electric power systems. Distortion factor is a closely related term and …
