摘要：
This paper studies and designs a wide-band current transformer, analyzes the structure of the wide-band current transformer, and establishes an equivalent circuit model. Furthermore, It gives the error analysis and error formula derivation, proposes a design scheme to reduce the error for wide-band current, and develops a wide-band current transformer prototype. Finally the performance test is given.
