- Harmonic Mitigation Transformers
Harmonic Mitigation Transformers are specifically designed to reduce harmonic distortion caused by non-linear loads such as variable frequency drives (VFDs), rectifiers, and inverter-based systems.
These transformers improve overall power quality, reduce system losses, and enhance the performance and lifespan of connected equipment.
ESTA Harmonic Mitigation Transformers are engineered for high harmonic suppression efficiency, stable operation, and reliable performance in demanding industrial and data-driven environments.
