3 Day Electrical Signature Analysis Training Course - Level I
Course Type: On-Site Classroom
Course Number: 10015
Three days, at the customers’ site, of Electrical Signature Analysis (ESA), Energized Motor Testing & Training. This training introduces you to ESA (energized motor testing). This course presents the basic theories and principles necessary to understand the concepts and principles associated with this technology. How ESA uses the motors supply voltage and operating current to detect & identifies faults in the motor system. It teaches the types of faults, and guidelines which can and can’t be detected with this motor testing method.
This course uses real world machinery data to teach the students how to operate and understand the basic principles of the ESA software. The principles presented include but are not limited to the development and interpretation of the Fast Fourier Transform (FFT), including an understanding of the importance of spectral resolution, causes and interpretation of sidebands and harmonics in the voltage & current spectrum. It provides an introduction into using the 3 phase PQ measurements and how to combine with the FFT displays to quickly and accurately identify faults in the motor system. It prepares you to evaluate single phase and three phase AC Induction motor systems to improve the reliability and uptime of your plant using the ATPOL II™ analyzer, Power System Manager (PSM) & ALL-TEST Pro ESA software.
This course uses the ALL-TEST Pro instruments, but the theories and principles presented are applicable for all energized motor testing systems. Course materials include Workbook, ESA 5.0 Software, & ESA Exercise Disk. PC (Laptop) with administrative access (Must run Windows XP or later) provided by the student.
Upon successful completion of this course students should be able to:
- Understand how to integrate ESA into a new or existing predictive maintenance programs (PdM) to identify & evaluate developing faults or existing faults
- Identify which electrical machines ESA can be performed on
