NETA Article Neutral and Ground Harmonic Induced Power Losses and Correction

In commercial and industrial power systems, harmonic currents can create
a variety of issues, including increased power losses and potential damage
to equipment. This article describes the various types of power losses
associated with neutral and ground harmonic currents with a focus on
resistive losses, transformer losses, and dielectric losses in distribution and
power factor correction capacitors, and how these losses can be corrected.
Several case studies on overall plant energy consumption are presented
with most energy and emission improvements well over 5%.
