High frequency effects in current measurement using Rogowski coils

Rogowski transducers are often used for measuring high frequency currents. It is not generally recognised that at very high frequencies the measurement is position sensitive. Furthermore the coil propagation time delay increases with frequency thereby reducing the expected bandwidth. This paper inve...

Description
Summary:Rogowski transducers are often used for measuring high frequency currents. It is not generally recognised that at very high frequencies the measurement is position sensitive. Furthermore the coil propagation time delay increases with frequency thereby reducing the expected bandwidth. This paper investigates these effects and presents some experimental verification
