Overview

ABB's Guard III Harmonic Mitigating Transformers (HMT), SKU 9T77H9874G03, are designed to eliminate harmonic distortion and enhance power quality in industrial electrical systems. These UL-listed, dry-type transformers feature a zigzag secondary winding topology specifically engineered to cancel triplen harmonics (3rd, 9th, 15th) and significantly reduce neutral current. This mitigation directly lowers energy losses associated with harmonic heating, improving overall system efficiency and extending equipment lifespan. The Guard III HMT maintains DOE 2016 energy efficiency standards even under harmonic loads, offering tangible operational savings. Constructed with copper coils, these transformers provide excellent thermal stability, available with either 115°C or 150°C temperature rise options. They include an electrostatic shield for enhanced noise isolation. The Guard III HMT is qualified to meet the stringent seismic requirements of IEEE-693-2005 and IBC-2021/CBC 2022, ensuring reliability in critical installations. Typical configurations include a 208V Delta primary and a 208Y/120V secondary with ±2.5% taps, available in ratings from 15kVA to 75kVA. Specific models like the 9T17C1451G33 offer 15kVA capacity with a 115°C rise. These transformers are ideal for applications with non-linear loads, such as data centers, healthcare facilities, and manufacturing plants utilizing VFDs, UPS systems, and LED lighting. By reducing transformer overheating by up to 50% compared to standard units, the Guard III HMT minimizes maintenance needs and prolongs the service life of connected equipment. They are compatible with standard 50/60Hz distribution systems and are RoHS/REACH compliant. Manufactured in the USA.
