Overview

This ABB K-Factor Transformer (SKU 9T14A1003G34) is a three-phase, 45kVA unit designed to reliably manage the thermal stresses and operational challenges associated with harmonic currents in electrical systems. Featuring aluminum windings and an 115°C temperature rise rating, it converts 480V Delta input to 208Y/120V output. This transformer is specifically engineered to withstand the effects of harmonics, not eliminate them, ensuring dependable power delivery for non-linear loads. Its construction includes a unique core and coil design utilizing grain-oriented, annealed silicon steel, with core and coil assemblies mounted on neoprene isolation pads to minimize vibration. Standard features include full-width copper electrostatic shielding between primary and secondary windings, providing up to 120 dB common mode noise attenuation and up to 30 dB transverse mode noise attenuation. The neutral and lugs are rated to handle 200% of the secondary full load current, crucial for systems with significant non-linear loads. Integrated flexible copper ground straps (Type QL) and lifting eyes facilitate installation. This K4-rated transformer is suitable for applications with up to 50% of loads generating harmonics, such as induction heating, SCR drives, and AC drives. It meets DOE 2016 efficiency standards, is UL Listed, and Energy Verified. Additionally, it is qualified to the seismic requirements of IEEE-693-2005, IBC-2021, and CBC 2022, making it suitable for critical infrastructure. The K-factor rating ensures it addresses temperature rise issues when supplying non-linear loads and withstands mechanical stresses caused by harmonic content. It is manufactured in the US.
