Using Rogowski coils inside protective relays

2013 66th Annual Conference for Protective Relay Engineers, 2013
Traditionally, microprocessor-based relays incorporate a secondary current transformer to convert the 5 A or 1 A input current to a lower level for input to an analog-to-digital (A/D) converter as part of the input processing. The limits of this input circuit are well known, and relay designers take them into account when determining operating ...

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.

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.
