Learn how to limit impacts of non-linear loads and harmonics in this white paper.

VFD options to meet IEEE 519 standards

Originally published in 1981 and most recently updated in 2014, IEEE 519 is a recommended standard to help reduce the negative impacts of non-linear loads on electronics and control systems on the same grid as the source of harmonic distortion. Water and wastewater operations employ many large nonlinear loads using variable frequency drives (VFDs) that are often the sources of harmonic distortion. IEEE recommends limits of 5-8% total harmonic distortion (THD) to the protect assets on the grid.
