Electrical Harmonics are a form of electrical liter or contamination within your distribution system.  In many instances they are misunderstood, feared or ignored.  With a basic understanding of how the harmonic currents are generated, the level at which they become a concern and the resolutions for abatement the industrial or municipal user can continue to apply and use non-linear power device with confidence.

AC motors have been used with Variable Frequency Drives for many years and with great success.  Utilizing a VFD in lieu of a traditional starter or even soft starter reduces in rush currents, prevents mechanical stresses on the driven equipment and infrastructure and also may result in great energy savings.  When the motor is powered by this type of control, consideration should be taken to ensure a good installation by knowing the concerns of utilizing this type of control and reviewing the required grounding requirements, grounding products and solutions.

Although Variable Frequency Drives (VFDs) are common in water and wastewater treatment plants for collection and distribution systems, the value they provide and how to properly select and use them are often not fully understood.  This presentation will demystify VFDs, providing a better understanding as to where and why you would use them.
