The calibration of transient current sensors is fundamental for the reliability of high current, short-circuit tests. The test can be performed with prospective or withstand current, but in both cases, the dynamic behavior of the current sensors has to be investigated, due to his influence on the scale factor value. The requirements of the IEC 62475 standard can be achieved with a calibration in transient conditions, performed with an approved reference measuring system. In this work a most performance measuring system is presented, for the improvement of INRIM high transient current measuring capability.
