Analysis of precision Rogowski coil via analytical method and effective cross section parameter

In this paper, we present a parametric analysis of Rogowski coil via an analytical method. Off-center and tilt angle of the primary wire together with coil geometry and number of turns are considered for our study cases. Results are obtained on the basis of the partial inductance method. Effective cross section of the coil appears as a promising novel parameter to characterize the performance of the transducer
