Aiming at the problem that the signal noise ratio (SNR) can’t meet the requirement due to electromagnetic interference in the measurement of coupling current of transmission cable core line in electromagnetic pulse environment, a shielded core line pulse current probe is designed and developed. This paper introduces the measuring principle of the probe, the structure characteristics and development situation, given the characteristics of the probe sensitivity and parameters, such as spectrum method and the calibration parameters, and analyzes its usage in the experimental results show that the design of shielded conductor pulse current probe based on the structure of the original transmission has a better ability to resist electromagnetic interference and pulse signal measurement capability.
