ABSTRACT:
A current detector comprises a primary current transformer (21) having a core made of silicon steel sheets and permalloy sheets overlapping each other, together with secondary current transformers (22) and (23) having cores made, respectively, of silicon steel and permalloy sheets. As a result, the detector exhibits linear current transformation throughout any current range, so that current detection errors are minimized.
