What is a harmonic filter?
Non-linear loads — VFDs, UPS systems, rectifiers and LED drivers — draw current in pulses, distorting the supply waveform. Harmonic filters remove those distortion currents, lowering total harmonic distortion (THD) so cables, transformers and capacitors stop running hot.
We supply ENTES passive filters where the harmonic profile is stable and known, and active filters where the spectrum varies with the load — each sized from your measured harmonic survey.

Harmonic Filter — FAQs
Do I need a harmonic filter or a detuned reactor?
A detuned reactor protects capacitors from resonance but does not materially reduce harmonics on your supply. If you need to lower THD — to meet a utility limit or stop equipment overheating — you need a harmonic filter.
Passive or active harmonic filter?
Passive filters are cost-effective where the spectrum is stable and dominated by known orders. Active filters track and cancel a changing spectrum, suiting plants with mixed or variable non-linear loads.
How do you size a harmonic filter?
From a power-quality survey: we log the harmonic spectrum and magnitudes at the point of connection, then size the filter to bring THD within the target. We can carry out that survey for you.
