MotorDoc Vlog 76 Evaluation of Wind Turbine Electrical and Mechanical Defects Due to Nacelle Circulating Currents

Based on Dr. Penrose’s IEEE EIC paper ‘Evaluation of Wind Turbine Electrical and Mechanical Defects Due to Nacelle Circulating Currents,’ as the practice session for the presentation. Introduction to how to use the Relative Harm Index for bearing currents even with brushes and an overview of the impact of discharge on main bearings, gearbox bearings and gears, and generator bearings and windings. Also includes a novel way to identify the severity and existence of shaft currents with straight ground readings.
