Magnetic shielding of Rogowski coils

2017 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2017
This paper describes the impact of Rogowski coil (RC) construction imperfections on measurement errors. A procedure is shown for detecting RC non-homogeneity using a rotary dipole magnetic field inducing a current inside an RC. The influence of RC magnetic shielding on reducing spurious fields is described.

Application of a Rogowski Coil Sensor for Separating Internal and External Partial Discharge Pulses in Power Transformers

IEEE transactions on industrial electronics (1982. Print), 2023
Partial discharge (PD) measurement is an essential tool for evaluating the health condition of a transformer insulation system. The conventional PD measurement systems have a major drawback since they cannot discriminate the internal PD pulses and ...

Rogowski coils: theory and experimental results

Review of Scientific Instruments, 1979
The theory is given of the voltage output of a Rogowski coil excited by a current pulse flowing along the axis of the coil. In this theory the Rogowski coil is considered as a delay line. The results do not differ from those obtained usually by considering the coil as a voltage source dφ/dt with an inductive output impedance.

Rogowski coil current meters

IEEE Potentials, 2008
This study has analyzed the performance of an alternating electric current measuring system using a Rogowski coil as a transducer, applied to magnitudes of milliamps to hundreds of amperes. It has been noticed that for low amplitudes, as well as for low frequencies, noise interferes with precision.

A Digital Twin System of Capacitive DC Bank Using Rogowski Coil to Monitor Individual Capacitors

IEEE transactions on power electronics, 2023
The reliability of dc link capacitors is closely related to the operational safety of the whole power electronic system. To meet the application requirements, it is usually necessary to use a series or parallel structure of multiple capacitors to ...

Determination of Rogowski Coil Constant

2006 International Conference on Applied Electronics, 2006
Method of determination of Rogowski coil (RC) constant at 50 Hz frequency is described in the article. The RC constant determining dependence between output voltage and measured current is checked and also a phase displacement of these two quantities is measured. Analysis of measurement uncertainties is also presented.

Development of Lightning Detection System Using Large-diameter Rogowski Coil and its Performance Evaluation Results

2023 12th Asia-Pacific International Conference on Lightning (APL), 2023
A wind turbine installed in winter lightning areas is required to be equipped with a detection system that can accurately detect a lightning strike. The lighting detection systems using a large-diameter Rogowski coil with high measurement accuracy are ...

Bus bar embedded rogowski coil

2018 IEEE Applied Power Electronics Conference and Exposition (APEC), 2018
This paper presents a design procedure of a bus bar embedded Rogowski coil in a laminated bus bar from the viewpoint of geometry. The current sensor can detect a current waveform inside the laminated bus bar. The characteristics of the current sensor depend on the both the coil and the laminated bus bar geometry; therefore, the impact of the coil ...
