Series Description: SolaHD K-Factor transformers are designed to reduce the heating effects of harmonic currents created by loads like those shown in Chart A. The K-Factor rating is an index of the transformerÂ’s ability to withstand harmonic content while operating within the temperature limits of its insulating system. our K-Factor transformers have UL ratings of K-4, K-13, and K-20.
The SolaHD 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.
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.
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. |
- Energy Efficient Compliant to DOE 2016 1
- Conductors to carry harmonics of a K-rated load without exceeding insulation temperature ratings
- UL 1561 Listed up to K-20 rated protection
