    K-factor defines the transformers ability to operate within it's designed temperature class with a non-linear load.

    The K-13 is designed for 75% non-linear loading & provides a 200% neutral.

    K-factor is a weighting of the harmonic load currents according to their effects on transformer heating, as
    derived from ANSI/IEEE C57.110. A K-factor of 1.0 indicates a linear load (no harmonics). The higher the
    K-factor, the greater the harmonic heating effects.
