Overview

The Hammond Power SK3A0030KK4S is a 30 kVA, three-phase, K-Factor 4 transformer designed for energy efficiency and compliance with DOE2016 and NRCan 2019 standards. This transformer features aluminum windings and is shielded for enhanced performance. It is specifically engineered to address harmonic distortion issues commonly found in applications with non-linear loads, such as those driven by variable frequency drives (VFDs) or other electronic equipment. 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 K-Factor rating of 4 indicates its capability to handle significant harmonic currents without overheating or premature failure, a critical consideration for modern electrical systems. Manufactured by Hammond Power in the USA, this unit (SKU: SK3A0030KK4S) offers a reliable and compliant solution for facilities requiring robust power quality management. The aluminum wound construction contributes to its overall efficiency and cost-effectiveness. This transformer is an ideal choice for applications where power quality is paramount and energy savings are a priority.
