Overview

The Hammond Power SK3A1000KK4K is a 1000 kVA, three-phase, K-Factor 4 transformer designed for applications with significant harmonic distortion from non-linear loads. This energy-efficient unit is compliant with DOE 2016 and NRCan 2019 regulations, ensuring optimal performance and reduced energy consumption. Featuring copper windings for superior conductivity and durability, this transformer is built for reliability. The primary voltage is 480D PV, and the secondary voltage is 480Y/277 SV, making it suitable for a range of industrial power distribution needs. Its shielded design further enhances protection and operational integrity. Manufactured in the US, this transformer (SKU: SK3A1000KK4K) offers a robust solution for facilities experiencing harmonic issues, helping to prevent overheating and premature equipment failure. The K-Factor rating of 4 specifically addresses the challenges posed by electronic loads such as variable frequency drives (VFDs), LED lighting, and switching power supplies, by providing a higher capacity to handle the increased RMS current due to harmonic currents. This proactive approach to harmonic mitigation leads to extended equipment lifespan and improved system stability. The 600V class rating indicates its suitability for medium voltage applications.
