Harmonic Filters
Harmonics are multiples of a fundamental frequency. For example, in a 60 Hz system, the 5th harmonic is 300 Hz. The total amount of harmonics in a power system is referred to as Total Harmonic Distortion (THD).
Harmonics are caused by non-linear load devices such as variable frequency drives, AC to DC converters, and UPS systems. Harmonics when present in a power system, often result in higher voltages and currents. This condition is known as poor power quality.
Myron Zucker, Inc.'s Caltrap™ and Capacitrap
® series should be applied to loads that are mostly constant and harmonic mitigation is required.

The Autocapacitrap™ and the ZT Capacitrap should be applied where the need for harmonic mitigation varies.
Automatically-switched passive filter for loads that vary; located at plant distribution center or service entrance.
