Welcome to Harmonics Limited

The Industry Leader in Harmonic Suppression Technology
Harmonics Limited (HL) is the recognized authority on mitigating harmonic currents in power distribution systems and is the leading provider of Harmonic Suppression Systems (HSS). Our proven and patented technology eliminates the formation of the damaging 3rd harmonic current generated by non-linear computer loads in today's commercial and industrial facilities. HSS enables both new and existing transformers to perform with increased reliability and reduced operating costs.


Retrofit existing transformers for immediate energy and cost savings.
Build HSS into new installations for full capacity at less cost.
Harmonic Suppression Technology for parallel generator applications.

"Green" Your Building
Save Energy… Reduce Costs

With HSS technology, you will recapture wasted electrical capacity and lower operating costs while reducing carbon emissions from currently operating power distribution systems as well as in new installations. These measurable and sustaining energy savings may help buildings achieve LEED certification and deliver reduced environmental impact. This compelling value proposition yields a dramatic initial ROI, with substantial cost savings and environmental benefits sustained over the life of the facility.
