FAQs
This transformer is designed for three-phase power distribution with copper windings and an EE enclosure style. Plan for adequate ventilation, ensure compatible KT-13 core assembly, and verify space for the unit’s footprint in switchgear or distribution panels. Check the site’s voltage stability and optimize tap settings (+2.5% / -2.5%) to maintain acceptable secondary voltage under load variations.
The model provides taps at +2.5% and -2.5% to compensate for voltage drop or rise due to long feeders, motor starts, or fluctuating loads. Selecting the appropriate tap reduces secondary voltage excursions, minimizes nuisance tripping, and improves power quality for downstream equipment like drives and controls.
Routine inspection should focus on insulation integrity, winding connections, and cooling paths. With copper windings, monitor for oxidation and ensure copper conductors remain tight to prevent overheating. Verify ventilation effectiveness in the enclosure, inspect taps for proper operation, and review insulation ratings to confirm continued compliance with operating temperature margins.
Ideal for commercial distributions, data centers, manufacturing lines, and distribution centers requiring stable voltage through variable loads. The 75 kVA rating, 480 V/208Y-120 V outputs, and KT-13 core with ventilated cooling support reliable power conversion in environments where space, heat management, and voltage regulation are critical.
Engineers can expect improved power quality, reduced unexpected downtime, and longer asset life due to stable voltages and better heat management. Copper windings and a designed insulation system contribute to higher efficiency and lower maintenance costs, while voltage taps help minimize energy waste during peak and off-peak periods, supporting a lower total cost of ownership.
