  • K- Factor - Canada Transformers dry-type electrical ...

    Understanding Transformer 'K Factor Rating' A K-Factor rating is an index of the transformers ability to supply harmonic content in its load current while operating within it temperature limits. For Dry Type Transformers a K-Factor calculation is made to determine the amount of the Harmonic Content present in a power system.

  • 3.5.2 Selection and Rating of Transformers

    Many power quality meters read the K-factor of the load current directly. Once the K-factor of the load is known, it is a simple matter to specify a transformer with a higher K-rating from the standard range of 4, 9, 13, 20, 30, 40, 50. Note that a pure linear load – one that draws a sinusoidal current – would have a K-factor of unity. A higher
