K-Factor Rated Transformers are specifically engineered to handle the harmonic currents generated by non-linear loads such as variable frequency drives (VFDs), uninterruptible power supplies (UPS), computers, and other electronic equipment. These transformers are designed to deliver clean, reliable power while minimizing overheating, voltage distortion, and premature insulation failure caused by harmonic content.
Constructed with low-loss core steel, precision-wound conductors, and advanced thermal management systems, these K-Factor Rated Transformers provide superior performance under harmonic loading conditions. Their optimized winding geometry and magnetic design reduce eddy current losses, improve voltage regulation, and ensure long-term reliability even in the most demanding environments.
Available in K-Factor ratings from K-4 through K-20 and beyond, these transformers are built and tested to meet or exceed CSA and UL standards. Standard and custom designs are offered for both single-phase and three-phase configurations, ensuring compatibility with modern power systems and compliance with IEEE C57.110 guidelines — delivering efficiency, durability, and peace of mind in harmonic-rich electrical systems.
