Harmonic Distortion

Harmonic distortion is the resulting non-sinusoidal current waveform generated by a non-linear load. The most common non-linear load is a pulse rectifier, which is used in most switch mode power supplies, variable speed drives and uninterruptible power supplies. The distorted current waveform generates a distorted source voltage due to the system (electrical power system) impedance. A distorted waveform can be analyzed by decomposing it into a fundamental component (line frequency) and higher frequency components of varying amplitude. The effects of harmonic distortion on metallized film capacitors are (1) higher operating temperature because of higher I2R losses, and (2) higher voltage stress on the dielectric. Both of these factors will shorten the life of a capacitor dramatically. All Aerovox Power Factor Correction capacitors are designed to handle harmonic currents, however, Aerovox also offers capacitors that are custom designed for systems with high harmonic distortion. By using our high-harmonic capacitors in your harmonic rich application, you will have a more robust construction compared to using standard capacitors in the same application.

Construction

All Aerovox Power Factor Capacitors are impregnated with a dielectric fluid to give added insulation, excellent corona protection and a moisture barrier. The dielectric fluid is considered a green (benign), environmentally friendly material. All capacitors are 100% leak tested. Aerovox products do not contain PCBs.
