Continuous calibration of Rogowski coil current transducer

Analog Integrated Circuits and Signal Processing, 2016
Rogowski coils (RC) intended for high-accuracy contactless current measurement ask for precise sensor geometry and specific conditions, such as a centered primary conductor. To release these constraints, we propose in this paper a recently patented continuous calibration system which features a reference conductor added coaxially to the primary ...

Volume Minimization of Current Type ACC with Rogowski Coil

Applied Power Electronics Conference
This paper proposes a current type active common-mode noise canceller (ACC) using a Rogowski coil for common-mode (CM) noise detection. The proposed method reduces the volume of a noise filter more than that of conventional methods.

FE based eccentricity analysis of Rogowski Coil

2016 IEEE 1st International Conference on Power Electronics, Intelligent Control and Energy Systems (ICPEICES), 2016
The Rogowski Coil (RC) has air as core around which coil is wound. It works on the principle of Faraday's and Ampere's law. RC can be used to measure both high speed impulse and alternating currents. RC offers some very important properties like wide bandwidth, galvanic isolation, linearity, lightness and cheap.

Design and Modeling of a Two-Winding Rogowski Coil Sensor for Measuring Three-Phase Currents of a Motor Fed Through a Three-Core Cable

IEEE Sensors Journal, 2021
In this article, three-phase motor currents pass through a three-core cable are measured using a two-winding Rogowski coil. The two-winding Rogowski coil is externally fitted around the three-core cable without the need for removing its insulation layers.
