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.

Reducing Costs with ESA and MCA™ Technology
More than 300 million electric motors are used in infrastructure, large buildings, and industry globally. These motors account for about 2/3rds of the industrial power consumption. Electricity is required in almost all areas of the plant to provide the driving force that either operates the equipment that produces the products or provides the services that the plant’s equipment was built to perform..
