Abstract :
This paper presents a low cost methodology to measure common mode (CM) currents in and induction motor fed by a speed drive. These measurements were made with a Pearson current transformer and a Rogowski coil, which allow to find the highest resolution and sensitivity currents in an induction motor. Finally, experimental results are shown, as well as a data comparative analysis.
