Error Characteristic Study and Experiment of Inductive Current Divider
As a high accuracy and high stability current ratio standard, inductive current divider(ICD) can be used in the calibration of current transformer and the range extension of current comparator,which isSespecially suitable for traceability of power frequency miniature current. In this context,it is necessary to explore error characteristic of ICD. The T-net-work equivalent circuit and Error expression of ICD is derived by this paper. And theSparameters which can influence the error performance of ICD is analysed inStheoretical.The experiment is conducted at last. BasedSonSthat, the conclusion of error characteristic of ICD is put forword by this paper,which isSof great significance to guiding the design and calibration of ICD。
