The increasingly sophisticated motor testing technologies used today quickly identify anomalies and mechanisms leading to motor failure. In this presentation, Don Donofrio, veteran instructor and consultant for The Snell Group, an internationally recognized expert in electric motor testing training and research, demonstrates the methods used for de-energized and energized motor testing. These methods are powered by completely different technologies, which he will talk through. Donofrio also will cover static winding, circuit, and insulation assessment methods, and will discuss power quality, current signature, in-rush, and electrical signature analysis. He will leverage several case studies to illustrate the effectiveness of these advanced motor testing capabilities.
