K-Rated Transformers

What is K-factor?

• K-factor is a value how much transformer can withstand harmonics without increase in maximum temperature value. A standard transformer cannot handle harmonics due to non linear loads. When harmonics enter into the transformer the core gets saturated as a result it produces lots of heat and failure of transformers.
• K-rating differs according to harmonic levels like K-1, K-4, K-7, K-13, K-20.
