Within the pumping community, variable frequency drives (VFDs) have become an accepted control method for flow, pressure, and level regulation. The practical application of VFDs for control and tremendous energy savings may be overshadowed by the feasibility of power harmonic problems resulting from the use of these same VFDs.

This harmonic issue will be presented in an open and friendly discussion supported with a deliverable PowerPoint of 35 slides. We will start the presentation on a very basic note of "Why worry, what's there to be concerned about?" to document issues ranging from unexpected downtime to catastrophic failures.

Defining the problems will provide the gateway to discussing true harmonic abatement, utilizing readily available industry products such as line reactors, filters, and industrial grade variable frequency drives from competitive vendors, ensuring that you will have "Clean Power at the End of the Line".
