PPT-Common Cures for Harmonics

Larry Stanley RSENashvilleTN Harmonics What Nonlinear loads draw nonsinusoidal current from a sinusoidal line current doesnt look like voltage Nonincandescent lighting. Harmonics are enerated in the sy stem Gener all y the effect of harmonics is studied in olta e or current The current harmonics flow in the sy stem enerates olta e harmonics whic h resul ts into pow er harmonics Pow er harmonics are than measured by http://www.youtube.com/watch?v=9cKnUFZjs8k.

What are real sounds composed of?. Virtually all sounds are composed of several (or many) frequencies all going at once. Some level of harmonics on the network are acceptable and to eliminate them completely would not be practicable. The issue is to find out at what level for a particular site is an acceptable condition Learning Goal. We are learning to use prime factorization to identify common factors and common multiples.
