| Abstract: | In order to solve the problem of high pulse current calibration from 1 to 100 kA,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 1~100 kA and duration of 20μs^100 ms.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%. |
| Keywords: | metrology pulse current pulse shunt fiber-optic current sensor Rogowski coil calibration |
