Active Harmonic Filter Servicing

Service and repair Active Harmonic Filters to improve your AHF's performance and prevent system degradation.

Active Harmonic Filters house intricate electrical components that are designed to mitigate harmonic voltages. Over time, the electrical components may deteriorate, and dust will gather in the unit. This will result in a decline in your Active Harmonic Filter's performance and lifespan. Keep your Active Harmonic Filter running at its optimal condition by making an appointment with our team for an Active Harmonic Filter service.

Why Service an Active Harmonic Filter? 

Active Harmonic Filters contain complex electrical components that work together to eliminate harmonics up to the fiftieth harmonic (2500Hz). A properly installed and serviced Active Harmonic Filter can help to reduce electricity bills, and reduce the circulation of neutral current to avoid overheating, insulation loss and unwanted tripping.  Like any piece of equipment, regular maintenance is essential to ensure optimal performance levels are maintained and the system is doing the job it was installed to do. 


If neglected, Active Harmonic Filters may malfunction. Dust and debris may also gather in the unit over time, reducing the performance of the Active Harmonic Filters.

  • Testimonial from Rupe Virk, Head of Projects Jalplas

    In early 2020 our site in Thomastown was experiencing power quality issues that was affecting our critical manufacturing equipment. After contacting Quality Energy and having them conduct a Power Quality study, it was determined we required a 200A Active Harmonic Filter to help eliminate our harmonic pollution and protect our entire infostructure. Quality Energy designed, installed and now maintain our Active Harmonic Filter and we have had a clean bill of health since the installation took place.

  • Testimonial from Chris James, Kurv Living

    In June 2020, Kurv Living were faced with several power outages due to the quality of the power entering our manufacturing facility. After completing extensive Power Quality diagnostics, Quality Energy determined that we had high harmonic levels that were causing our critical machinery to shut down. Quality Energy then installed a 200Amp Active Harmonic Filter in September of the same year and we haven’t had any issues since.
