K-factor is a weighting of the harmonic load currents according to their effects on transformer heating, as derived from ansi/ieee c57110 the higher the k-factor, the greater the harmonic heating effects there are many different loads such as computers, solidstate devices and motors which cause a non linear load. K factor electrical engineering. Iec 60364-5-54 gives the following formula for the calculation of the factor k: k = q c (
