Calibration of Rogowski Coils with an Integrator at High Currents
Original language description
This paper describes the calibration of a Rogowski coil (RC) with an integrator assigned for current measurement in the range up to 30 kA at 50 Hz mains frequency. A current loop with 10 turns with a current of 3 kA was used for calibration. The magneticfield generated in this way differs from the field of one turn placed in the centre and passed with a current of 30 kA. The influence of unevenness of winding and the cross-section of the RC may cause a calibration error when using a current loop. The difference in the results between using a current loop and one turn and the measurement uncertainties are given below. Calculations of the mutual inductances of typical RCs and their uncertainties are presented in the Appendix.
