K - Rated Isolation Transformers

K - Rated Isolation Transformers address the problems caused by non-linear loads and harmonics. They also compensate for stresses on a transformer’s winding insulation which prevents insulation breakdown and premature failure. The net result is longer transformer life. 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.
