Motor Testing
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.

The Scope and Application of Electrical Signature Analysis in Windpower
Electrical Signature Analysis (ESA) was initially developed at Oak Ridge National Labs (ORNL) in the 1980s as a method for evaluating bearings and gears in motor operated valves in the nuclear power industry. In 1992, the technology was licensed into general industry for applications in utilities and commercial applications...
