K-factor transformer SolaHD

The Sola/Hevi-Duty K-Factor design is a specialized transformer that offers these benefits:


Conductors capable of carrying the harmonic currents of non-linear loads without exceeding the temperature rating of the insulation system. Paralleled conductors are used to reduce and control skin effect losses.


A transformer design that takes into account the increase in naturally occurring "stray" losses caused by non-linear loads. These losses cause standard transformers to dramatically overheat and substantially shorten design life. The K-Factor is designed to function within safe operating temperatures.


A core and coil design that manages the DC flux caused by triplen harmonics*. As these harmonics increase, they cause additional current to circulate in the delta winding. This produces a DC flux in the core which leads to core saturation, voltage instability and overheating.


K-Factor transformers are UL 1561 listed.


Designed to supply non-linear loads without overheating the windings or saturating the core.


All Sola/Hevi-Duty K-Factor transformers have a rated temperature rise of 150°C.
