Temperature characterisation of an optically interrogated Rogowski coil [PDF]
An investigation into the performance of an optically-interrogated Rogowski coil over temperatures up to 80 °C is presented. Preliminary thermal tests reveal that the sensor response is temperature-dependent and the measurement errors are increased at higher temperatures.

A Rogowski-Chattock coil : sources of error [PDF]
The local magnetic field is measured by means of magnetic sensors, such as a Rogowski-Chattock coil. The main advantage of the Rogowski coil is its capability to measure the field strength directly at the sample surface because both ends of the coil can be installed very close to the specimen surface.
