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.

Basics of Electrical Signature Analysis
Modern electrical signature analysis is no more challenging than vibration analysis. There are differences including using an electric motor or generator’s air gap as the transducer and evaluating an amplitude modulated signal.
