HARMONIX active harmonic filter cabinet in an industrial facility

Cleaner Power

For Every Load

The Power Quality

Challenge

Non-linear equipment can introduce harmonic currents into an electrical network. HARMONIX is designed to measure these disturbances and actively compensate for them in real time.

Active compensation

in real time

HARMONIX is connected in parallel with the loads being compensated. It measures the current produced by non-linear loads and injects compensating harmonic currents with the opposite phase angle. This counteracts the harmonic components, allowing the electrical system to supply primarily the fundamental-frequency current.
