HARMONIC DISTORTION PROBLEMS
Starting in the late 1970's commercial, institutional, and industrial plants have experienced a tremendous growth in the use of equipment that can generate "harmonic" distortion in power systems. Some examples of such equipment will include DC drives, AC variable frequency drives, rectifiers, induction furnaces, and UPS systems. This harmonic distortion develops a current wave shape which results in higher than normal RMS amperes (and heat) which will result in nuisance fuse blowing, circuit breaker tripping, over-heated transformers, and premature capacitor failure.
If a facility has but a few pieces of the above-mentioned equipment in use, Myron Zucker, Inc. can pinpoint the harmonic number and amplitude present in the system. If the facility is a large one with many sources of harmonic distortion, then a complete audit of the total electrical systems with a harmonic analysis must be made. We can provide such services.
The solution to all of the above is the installation of harmonic filters that not only correct or improve the power factor, but also prevent harmonics from damaging existing equipment. We have developed the Caltrap™ brand harmonic filters for application at the source of harmonic-producing equipment. We also have the larger Capacitrap® brand harmonic filters (large filter banks) to provide overall system correction when many types of harmonic-producing equipment exist. Our AutocapacitrapTM provides overall system correction where loads vary.
This has become quite a specialized field, and we consider ourselves as leaders in low-voltage filter application. We are ready to help you eliminate your "Dirty Power" problems! Let us furnish you our application guide for solving harmonic distortion problems.
