In this live webinar we will go beyond the usual discussions of electric motors and rotor bar issues generally associated with current signature analysis. Electrical Signature Analysis (ESA) technology is used to review incoming power quality, the machine through the entire powertrain with the ability to troubleshoot and trend electrical and mechanical defects as well as identifying energy consumption impact of maintenance actions. In this presentation, we will discuss how ESA is used to evaluate electric motors, couplings and gearboxes of several types including speed reducers, increasers and cooling tower boxes.
1. Definitions related to ESA and MCSA and how voltage, current and power signatures are analyzed
2. How electrical and mechanical conditions are calculated in ESA/MCSA
3. How gearbox components are calculated and analyzed
4. How these can be evaluated with either MCSA-only devices (some vibration analyzers) and a variety of commercially available ESA devices
