Abstract

In the paper, the performance of current measurement devices based on Rogowski coils is analysed. In order to show the influence of the slope of the current waveform di/dt on the measurement accuracy, the results of a set of simulations in  GNU Octave and LTSpice® are presented. The simulations are complemented by some measurements, which were done with different smart meters using the Rogowski technology for current measurement. It is demonstrated that potential measurement deviations are a reproducible physical characteristic of this measurement type. The paper presents simple tools easy to adjust to real conditions that e.g. appear in low voltage networks.
