Abstract :
Electrostatic interference through capacitive coupling onto a Rogowski coil causes unwanted pick-up noise on the output of the integrator. An electrostatic screen fitted to a Rogowski coil reduces this interference. This paper discusses how to maximise the high frequency (hf) bandwidth of a Rogowski transducer with a screened coil.
