Overview

ABB's K-Factor Transformer, SKU 9T14A1001G33, is a dry-type transformer specifically designed to manage the thermal stresses caused by harmonic distortion in modern electrical systems. This transformer does not eliminate harmonics but is engineered to withstand their negative effects, ensuring reliable operation in environments with significant non-linear loads. Available with aluminum or copper windings and in multiple temperature rise ratings (150°C, 115°C, 80°C), it offers application flexibility. The 9T14A1001G33 meets DOE 2016 efficiency standards and is UL Listed and Energy Verified. It is also qualified to seismic requirements per IEEE-693-2005, IBC-2021, and CBC 2022. Key features include a grounded full-width copper electrostatic shield, providing common mode noise attenuation up to 120 dB and transverse mode noise attenuation up to 30 dB. The core and coil assembly utilizes grain-oriented, annealed silicon steel mounted on neoprene isolation pads for vibration resistance. Lifting eyes are integrated into the top core clamp for safe handling, and a flexible copper ground strap (Type QL) ensures proper grounding. Lug kits and copper ground bar kits are included on units up to 150kVA. The transformer's neutral and lugs are rated to handle 200% of rated secondary full load current. Ideal for commercial, industrial, and institutional facilities such as data centers, healthcare facilities, and manufacturing plants where harmonic distortion is a concern, this transformer ensures long-term reliability and operational efficiency.
