Commercial and Industrial Power System Losses and Mitigation through Neutral and Ground

Even in discussions related to power harmonics most engineers, let alone reliability and energy professionals, understand the potential losses through the system. When it comes to harmonic content in neutral and ground in single and three phase systems, and the related losses, there has been limited attention...

Systems Energy and Emissions Analysis with Electrical Signature Analysis

There are several ways to view the impact of maintenance practices using ESA and electrical measurements, the first is the use of simple overall kilowatt readings from a power analyzer or relay monitoring system; the second is the before and after readings from an ESA device that identifies kilowatt data by defect.
