50 Hz current measurements with Rogowski coils

Conference Digest Conference on Precision Electromagnetic Measurements, 2003
The applicability of Rogowski coils for high precision measurements of 50 Hz currents is studied. In the set-up, Rogowski coils serve as current sensors and the amplitude and phase are determined with a sampling voltmeter. Another measurement channel enables current ratio and electrical power measurements.

Interlocking Rogowski coils: a fool's transformer

Proceedings of Conference on Precision Electromagnetic Measurements Digest, 2002
We have constructed interlocking, air-core, toroidally-wound solenoids. In principle, there should be no coupling between these Rogowski coils (in the absence of return loop and capacitive effects). We have searched for a mutual inductance between two such interlocking coils and report preliminary results. >

High Frequency Rogowski Coil Response Characteristics

IEEE Transactions on Plasma Science, 1982
The high frequency response characteristics of differentiating and self-integrating Rogowski coils have been calculated for arbitrary values of the coil terminating resistance assuming Ampere's law to be valid. Effects due to a reactive terminating impedance are also discussed.
