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. However, most of the methods for calculating different conditions are very similar and you have an opportunity to look at the entire system at once. This means that you can determine not just degradation in either an electrical or mechanical component, but what part of the system is driving the degradation. In this webinar we will explore the concept of ESA from the basics of the transducer to how data is managed and evaluated. Basic motor evaluation and driven equipment evaluation will be discussed and demonstrated. There are several interactive online systems available for you to apply what you have learned during or after the class.
