K-FACTOR TRANSFORMER K factor has been a basis for measuring the capability of a transformer to carry nonlinear loads. It is the factor to determine whether the transformer can withstand transformer heating due to harmonic load currents. ANSI/IEEE Std.C57-110 is the primary reference when it comes to the discussion of k-factor in a transformer. Below are selected articles discussing the k-factor and the k-rated transformers. FAQs are also available for your reference to make yourself familiar with the nature of use of this k-factor for transformer. K-Factor Definition 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. When a non-linear load is supplied from a transformer, it is sometimes necessary to derate the transformer capacity to avoid overheating and subsequent ins...
