Overview

ABB Guard III Harmonic Mitigating Transformers (HMT), SKU 9T76H9874G03, are purpose-built to neutralize harmonic distortion in industrial power systems, a critical issue that degrades power quality and inflates energy costs. These transformers actively suppress harmonics, reducing heat losses and protecting sensitive equipment from damage or inefficiency. Unlike standard transformers, Guard III HMTs maintain DOE 2016 energy efficiency standards even under harmonic load conditions, delivering measurable energy savings and lower operational expenses. Constructed with copper coils and electrostatic shields, the Guard III HMT series ensures durability and superior performance in demanding environments. Available in 150°C Rise and 115°C Rise configurations, these three-phase transformers support input voltages of 208 Volts Delta and output voltages of 208Y/120 Volts. Standard kVA ratings include 15, 30, 45, and 75 kVA, with ±2.5% taps for precise voltage regulation. Frame sizes are optimized for compact installations, with approximate net weights ranging from 270 lbs (15 kVA) to 1010 lbs (75 kVA). Certified to UL standards and qualified for seismic resilience per IEEE-693-2005, IBC-2021, and CBC 2022, Guard III HMTs are engineered for reliability in high-risk zones. Their zigzag secondary design further enhances harmonic mitigation while providing flexibility for diverse system configurations. Made in the USA, these transformers are ideal for facilities prioritizing power quality, energy efficiency, and equipment longevity. Common applications include data centers, healthcare facilities, manufacturing plants, and commercial buildings where harmonic distortion poses operational risks.
