Written with the field technician, engineer, or reliability/maintenance manager in mind, Practical Electrical and Current Signature Analysis for Electrical Machinery and Systems is an essential working tool for the new and experienced ESA and MCSA practitioner. The book takes the practitioner well beyond the electric motor into incoming power, mechanical components, and driven equipment up to and including complete DFIG wind turbine and powertrain analysis and alternative energy transformers. It is based upon decades of field experience and practical research concluding with an overview of machine learning associated with basic motor data and present applications of ESA/MCSA IoT systems. Whether data collection or continuous monitoring regardless of the technician's choice of technology, you will understand the requirements, capabilities, and limitations to provide accurate prognostics. For managers and engineers who need to understand the capabilities of ESA/MCSA the book provides an easy-to-understand overview of the technology along with extensive real case studies.
