Isolation transformer

K-factor is defined as a ratio between the additional losses due to harmonics and the eddy current losses at 50Hz.
K-Factor is defined as a ratio between the additional losses due to harmonics and the eddy current losses at 50Hz. It is used to evaluate transformers for nonlinear loads. Transformers with a rated K-factor of 4, 7, 13, 20 and 30 are available.
The ANSIIEEEE C57.110 has derived a system of weighing how much harmonic load currents a transformer can handle without exceeding its maximum temperature rise level. A K factor of 1 indicates no harmonics, while a K factor of 50 is the harshest harmonic environment possible. Typically a K Factor of 13 is sufficient for most applications. K factor must be determined to calculate the right size transformer that is needed.
