K-factor transformers are designed to withstand harmonic currents, generally caused by non-linear loads that are connected to the main supply. These harmonic currents are usually the source of overheating issues in the cable and induction motors. They also increase the losses in the transformers.
Our K-factor transformer can help reduce the heating effect of harmonic currents by using conductors that are able to carry the harmonic currents of non-linear loads without exceeding the temperature rating of the insulation. They also compensate for stresses on a transformer’s winding insulation which prevents insulation breakdown and premature failure.
