Objetivos

The attendants will learn different electrical techniques for condition monitoring of electric motors. They will apply different methods based on current analysis for the diagnosis of faults in electric motors. These techniques will comprise both the classical methods (MCSA) as well as basic versions of modern transient-based tools (ATCSA). Moreover, they will learn the basics of partial discharge technique and the foundations of several off-line tests that commonly applied in the field to determine the condition of such machines.
