Harmonic Mitigating Transformers
Henka’s Harmonic Mitigating Transformers actively reduce voltage distortion and power losses caused by harmonic currents. Using zero-sequence flux cancellation and phase shifting, they lower total harmonic distortion (THD), improving system performance and meeting IEEE 519 standards.
Enjoy cleaner power and a more efficient electrical system with our harmonic-reducing transformers built for precision.

Technical Specifications
Tailor-Made Transformer Solutions
Henka’s Harmonic Mitigating Transformers (HMTs) come in three-phase capacities from 15 to 1,000kVA with a 1.2kV voltage class. Built with air-cooled copper or aluminum windings, a 220°C insulation system, and a 150°C temperature rise (optional 115°C or 80°C), they meet North American energy standards. Designed for non-sinusoidal loads, they support a K-factor up to 4 (higher options available) and offer +/-2 x 2.5% primary taps. Available in single, dual, or triple output configurations, they meet NEMA ST-20 sound levels and come in a durable ANSI 61 grey Type 1 or 3R enclosure.
CSA-certified, UL-listed, and ISO 9001:2015 compliant, Henka HMTs offer optional features like electrostatic shielding, custom enclosures, and specialized finishes.
