K Factor Transformers -  A K-factor  is a value used to determine how much harmonic current a transformer can handle without exceeding it’s maximum temperature rise level. When a k factor value is used in a transformer,  it is said to be K-rated.
A k-factor transformer is used to deal with harmonic generating loads. A k-factor transformer works by using double sized neutral conductors and either change the geometry of their conductors or use multiple conductors for the coils. Quality transformers are manufactured with high grade silicon steel, copper windings, and more air ducts.
