Linear Rogowski coil

Review of Scientific Instruments, 2017
Nowadays, the employment and development of fast current pulses require sophisticated systems to perform measurements. Rogowski coils are used to diagnose cylindrical shaped beams; therefore, they are designed and built with a toroidal structure. Recently, to perform experiments of radiofrequency biophysical stresses, flat transmission lines have been ...

MEMS Rogowski coil current sensor with spiral return coil

Electrical Engineering in Japan (English Translation of Denki Gakkai Ronbunshi), 2022
AbstractWe have developed a MEMS Rogowski coil current sensor with spiral return coil. The Rogowski coil is formed on a silicon substrate clockwise and counterclockwise from the edges, for current detection and external magnetic noise compensation (device size 10 × 10 × 0.3 mm3, spiral coil 135 turns, via diameter 100 μm).

Machinable Rogowski coil, design, and calibration

IEEE Transactions on Instrumentation and Measurement, 1996
Rogowski coils are special types of mutual inductors often used to measure high AC and transient currents. Traditional designs are reviewed. The significant sources of error associated with typical coil designs are examined. A "machinable Rogowski coil" is introduced and discussed. The reasoning behind critical design choices is discussed. The improved

On-site calibration of a current transformer using a Rogowski coil

2008 Conference on Precision Electromagnetic Measurements Digest, 2008
This paper describes a reference current-measuring system for the onsite calibration of high-voltage current transformers. The reference current-measuring system consists of a Rogowski coil, a current shunt, two digitizing voltmeters, and a computer to control the voltmeters.
