This paper presents a design and calibration of six novel linear side-looking “Rogowski” coils to measure impulse currents through plates. This special design of Rogowski coils enables the measurement of impulse currents in some applications, where such measurements are very difficult to be achieved using the toroidal Rogowski coils. The six designed coils are divided into two sets based on the coil-operating...
This paper describes a new method for optimizing both Rogowski coil’s temperature coefficient and its high frequency response. The proposed scheme is based on finding a value for coil termination resistance and for its temperature coefficient, which result in negligible change of coil output voltage versus temperature while still allowing for any damping ratio desired. The method is tested in a proof-of-concept...
