| Abstract: | This paper introduces the advantage.purpose，principle and design of self-integral Rogowski coil for ns-level current measurement.The response and distribute of Rogowski coil are discussed.The coil with a shield is treated as a distributed circuit.So that the toroidally wound coil acts as a delay line. The coil is calibrated.This coil could get the signal with rise time less than 2ns，value 10A～40kA，sensitivities about 1.4mv／A，pulsed width less than 200ns.The coll can be used in pulsed power technology for ns-level high current measurement. |
