Most AC electrical equipment in North America is designed for AC electricity at 60 Hz or alternating cycles per second. Any electrical current above 60Hz is called a harmonic. Harmonics are not only wasted power but can also damage equipment.
Traditional methods of correcting harmonics include capturing the harmonic and sending it to ground or using power to generate the inverse harmonic to cancel out the original harmonic.
captures broadband harmonics or electrical frequencies above 60 Hz and then recycles the wasted electricity back to 60 Hz. This reduces electrical losses and improves equipment longevity.
