The 15T3HF is a three-phase, 15 kVA dry-type transformer designed for electrical distribution. It features a primary voltage of 480V in a delta configuration and a secondary voltage of 208Y/120V in a four-wire wye configuration. Constructed with aluminum windings and an insulation system rated for 220°C, this transformer is built to meet high efficiency standards, achieving approximately 98% efficiency at 35% load. It has a NEMA 2 enclosure for indoor use and is rated for a temperature rise of 115°C. The transformer incorporates a natural convection cooling method and is designed to distribute higher voltages to reduce wire losses and voltage drops, while also adding source impedance to improve system stability.
