Abstract :
This paper establishes a methodology to measure Electric Discharge Machining (EDM) bearing currents in induction motors with supply from a speed drive (VSD - Drive). This paper studies the kinds of bearing currents caused by the joint operation of a motor-drive system, and establishes a methodology to measure EDM current, which includes design and construction of a Rogowski coil that allows detection and measurement of EDM bearing currents. Finally, laboratory tests are made to register, characterize and validate this methodology.
