Error characteristic study and experiment of inductive current divider
摘要
Abstract
As a high accuracy and high stability current ratio standard, inductive current divider (ICD) can be effectively used in the calibration of current transformer and the range extension of current comparator, which is especially suitable for traceability of power frequency miniature current.On this basis, it is necessary to explore error characteristic of ICD.The T-net-work equivalent circuit and error expression of ICD are derived in this paper, and the parameters which can influence the error performance of ICD are analyzed in theory.The experiment research is conducted at last.Based on this, the conclusion of error characteristic of ICD is put forward in this paper, which is of great significance to guide the design and calibration of ICD.关键词
