Harmonics No More | Consulting
Problems with capacitor operation and life, such as resonant conditions, capacitor-case expansion, and capacitor rupture. Most harmonics-related problems have one of two basic origins: current-wave distortion or voltage-wave distortion. A third factor, harmonic phase shift, results from a combination of the first two and is not as crucial.
