power systems designed to function at the fundamental frequency, which is 60-Hz in the United States, are prone to unsatisfactory operation and, at times, failure when subjected to voltages and currents that contain substantial harmonic <span id="frequency-elements.“>frequency elements. Very often, the operation of electrical equipment may seem normal, but under a certain combination of conditions, the impact of harmonics is enhanced, …

The adverse effects of harmonics in electrical power systems are very real, and failures related to voltage and current harmonics very often occur without warnings. When you have an indication that harmonics are present, your next step is to carry out testing to measure their level in the power system; you’ll need this information to determine what mitigation system to use.
