A Concise Analytical Formula of Mutual Inductance for Circular Rogowski Coil Revealing Spatial Distribution Characteristics of Mutual Inductance Deviation

IEEE Sensors Journal, 2022
Mutual inductance between primary wire and circular Rogowski coil varies with the position of primary conductor, the deviation of mutual inductance referred to center of circle causes the measurement error. Usually, the mutual inductance of Rogowski coil

Design of Shield Ring for UHV-class Gas-insulated Switchgear Spacer with Built-in Rogowski Coil based on Electromagnetic Interference Analysis

International Conference on Electric Power Equipment – Switching Technology, 2022
The main goal of this paper is to design the shield ring for the Rogowski coil embedded in the UHV-class gas-insulated switchgear (GIS) spacer. Because the UHV-class GIS spacer holds the individual conducting wires adjacent, the Rogowski coil can be ...

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
