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.
