It is established that neutral and ground harmonic content will load transformers and systems. Prior work has been limited as to the direct relationship of this additional loading on power consumption for a facility. Over the past 24 months applied research has been performed on the measured impact of neutral and ground harmonics and energy consumption in commercial and industrial facilities. In this paper we will discuss the application of an Onics Neutral Harmonic Filter in a single panel at a facility and the change in energy consumption before and after installation, as well as changes over a two-month period in similar loading conditions. Data collection for comparing neutral harmonic content was performed with an EMPATHâ„¢ data collection system. The addition of a test on the impact of remaining neutral harmonics is included related to timing and devices.
