Electrical and Current Signature Analysis of Electric Motors and Driven Equipment
The paper identifies the approach for electrical and mechanical conditions through direct and belt coupled applications and how driven equipment, and loads are evaluated through those coupling types. We will focus on two types of technologies including a 3-phase voltage and current ESA and a single-phase CSA system. The focus will be on CSA but will distinguish what the addition of voltage as part of the measurement will provide.
