Abstract—Electrical and current signature analysis (ESA/MCSA) techniques provide a valuable method for detecting defects in wind turbine generators, particularly in doubly-fed induction generator (DFIG) systems.  This paper explores the application of ESA/MCSA in identifying defects such as wye-ring fractures, bearing wear, and gearbox faults.  We discuss the data acquisition process, spectral analysis methodologies, and case…

Electrical Signature Analysis (ESA) is the method of using the electric machine magnetic field as the transducer as measured through voltage and current.  The method was originally developed by Oak Ridge National Labs in the late 1980s for the expressed purpose of fault detection of gear and bearing wear in driven equipment in addition to…

It is generally understood that lubrication must, by default, have an impact on equipment efficiency in terms of friction.  These losses, which are lumped into friction and windage in efficiency standards, such as IEEE Standard 112 Method B[1], which is one of the five types of electric machine losses: core losses (15-25%) and friction and…
