Abstract  In order to solve the problem of high pulse current calibration from 1 to 100kA, a high pulse current calibration system was established, and the research on high pulse current calibration and traceability technology were carried out. The calibration system consists of a high current pulse generator, a pulse shunt set, an optical fiber current sensor, a Rogowski coil current sensor, a broadband data acquisition system and a measurement software. The calibration system can be used to calibrate the pulsed high current generation/measurement system with pulse amplitude of 1~100kA and duration of 20μs~100ms. The calibration of Rogowski coil sensor, optical fiber current sensor and other measuring instruments can be carried out, and the calibration uncertainty is better than 1%.
