The reliable design of PCB Rogowski Coil current transformer

2006 International Conference on Power System Technology, 2006
PCB Rogowski coil has a particular structure that interconnects the conductive imprints on the upper and lower sides of the each printed circuit board by plated through holes and connects printed circuit boards in series by soldering points. Once a plated through hole or a soldering point falls, PCB Rogowski coil opens and outputs incorrect signal ...

PCB Rogowski coils for high di/dt current measurement

2000 IEEE 31st Annual Power Electronics Specialists Conference. Conference Proceedings (Cat. No.00CH37018), 2002
In order to measure di/dt in the range of 10 to 20 kA//spl mu/s, air cored coils can be used. The coil's natural frequency limits the bandwidth of this probe. PCB coils have a natural frequency of 10 MHz or more. Theoretical analysis and measurements with di/dt of 5 kA//spl mu/s and 500 A are presented, employing the PCB coil in a HOKA current probe.
