Title:
IRON CORE-ANNULAR ARRAY MULTI-RING MAGNETOSENSITIVE CURRENT SENSOR AND CURRENT MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/077900
Kind Code:
A1
Abstract:
An iron core-annular array multi-ring magnetosensitive current sensor and a current measurement method, the method comprising: using a first loop structure (101) to acquire a feedback current signal generated according to a first magnetic field signal generated by a primary side current; using a second loop structure (102) to measure a second magnetic field signal generated by the current of a wire in a coil; and using a digital processing unit (103) to calculate, according to the feedback current signal and the second magnetic field signal, the feature quantity that characterizes the current of the wire, and determining the current on the wire according to the feature quantity that characterizes the current of the wire.
