WEBINAR | 2 Dec 2026 | Practical benefits of centralized harmonic mitigation: Active Harmonic Filters vs. Active Front End drives
Variable Frequency Drives (VFDs) are essential in modern electrical installations, but the harmonics they generate must be considered early in system design. Choosing between a centralized Active Harmonic Filtering (AHF) solution and Active Front End (AFE) drives can affect engineering requirements, available space, system performance, and long-term costs.
In this webinar, Riku Kalliomaa, Head of Sales, Power Quality Products, and Niko Leväsluoto, Product Manager, Active Harmonic Filters, will explore the practical benefits of centralized harmonic mitigation and how it compares with Active Front End (AFE) drives.
They will discuss engineering considerations, including capacity and space reservations during the FEED phase, and share real-world examples of harmonic mitigation and resonance damping. The webinar will conclude with a live demonstration of the Merus® Harmonic Calculator.
