Overview

ABB’s K-Factor Transformer (SKU: 9T14A1005G03) is a dry-type, three-phase transformer engineered to withstand harmonic distortion in electrical systems without eliminating harmonics. Rated for 112.5 kVA with a 150°C temperature rise, this unit features aluminum windings and a grounded full-width copper electrostatic shield between primary and secondary windings to mitigate noise and transient voltages. The electrostatic shield provides common mode noise attenuation up to 120 dB and transverse mode attenuation up to 30 dB, ensuring clean power delivery to sensitive loads. Designed for environments with non-linear loads—such as induction heating, SCR drives, AC drives, and data processing equipment—the 9T14A1005G03 addresses the mechanical and thermal stresses caused by harmonic content. Its core and coil assembly uses grain-oriented, annealed silicon steel mounted on neoprene isolation pads to reduce vibration and extend operational life. The transformer includes lifting eyes, a flexible copper ground strap (Type QL), and a lug kit for easy installation. Compliant with DOE 2016 efficiency standards, UL Listed, and Energy Verified, this transformer meets the seismic requirements of IEEE-693-2005, IBC-2021, and CBC 2022, making it suitable for critical infrastructure in seismically active regions. Neutral and lugs are rated for 200% of the secondary full load current, providing additional capacity for harmonic-rich applications. Available in multiple K-factor ratings (K4, K13, K20) to match specific load profiles, the 9T14A1005G03 ensures reliable power distribution in hospitals, data centers, industrial facilities, and commercial buildings where harmonic distortion is a concern.
