Abstract :
A high precision Rogowski search coil (RSC) is proposed for monitoring of rotating electrical machines. The RSC includes several sets of printed circuit board Rogowski coil, in which any set includes two printed circuit boards with imprinted coils located adjacent to each other. The RSC offers a number of advantages including compact size, great accuracy, high bandwidth, low cost, and it is applicable even for already fabricated electric machine. Performance of the RSC is evaluated by some experiments.
