Overview

ABB's Guard III Harmonic Mitigating Transformers (HMT) (SKU: 9T77H9871G03) are engineered to provide superior power quality and energy efficiency in demanding industrial and commercial applications. These three-phase transformers are UL Listed and specifically designed to eliminate harmonic distortion, a common issue that degrades power quality and leads to increased energy losses, primarily through heat. By actively mitigating harmonics, the Guard III HMT ensures cleaner power, which enhances the longevity and reliability of connected equipment. Maintaining compliance with DOE 2016 energy efficiency standards, even under significant harmonic loads, is a key benefit. This means consistent performance and reduced operational costs. The HMT features copper coil options with either a 15°C or 150°C temperature rise, electrostatic shielding for enhanced protection, and zigzag transformer secondaries available in common phase shifts, offering flexibility for various system configurations. Input voltages are 208 Volts Delta, with an output of 208Y/120 Volts. Available kVA ratings range from 15 to 75 kVA, with tap settings of +2, -4: 2.5% for fine-tuning voltage. Approximate net weights vary by kVA rating, from 270 lbs for a 15 kVA unit to 1010 lbs for a 75 kVA unit. The Guard III HMT is built to withstand challenging conditions, evidenced by its qualification to stringent seismic requirements, including IEEE-693-2005, IBC-2021, and CBC 2022. This makes it an ideal choice for installations in seismically active regions. Applications include data centers, healthcare facilities, manufacturing plants, and other critical infrastructure where uninterrupted, high-quality power is essential for operations and equipment protection.
