Inductive　current　divider　has　high　accuracy　and　high　stability　of　current　ratio,　which　is　widely　used　in　the　verification　of　current　transformer　and　other　fields.　In　this　paper,　a　method　for　calibrating　inductive　current　divider　based　on　the　principle　of　reference　current　increment　method　is　proposed,　and　the　basic　principle　of　reference　current　increment　method　is　introduced;　the　design　principles　of　reference　current　transformer　and　differential　current　measurement　circuit　are　analyzed;　the　experimental　circuit　for　the　self-calibration　of　the　inductive　current　divider　is　built;　the　developed　two-stage　inductive　current　divider　is　calibrated　in　the　frequency　ränge　of　50　Hz　~　1　kHz,　and　the　uncertainty　of　the　calibration　result　is　analyzed.　The　experimental　results　show　that,　in　the　frequency　ränge　of　50　Hz　~　1　kHz,　the　measurement　synthetic　Standard　uncertainty　of　the　ratio　difference　of　the　two-stage　inductive　current　divider　is　better　than　5x10-8　A/A,　and　the　measurement　synthetic　Standard　uncertainty　of　the　phase　difference　is　better　than　1　X　10-7　rad.　©　2024　Harbin　Jinhe　Electrical　Measurement　&　Instrumentation　Magazine　Publishing　Co.,　Ltd..　All　rights　reserved.
