Method and system for detecting core faults |
摘要 |
A method for detecting core faults includes: positioning a magnetic yoke near at least one tooth of the core, the magnetic yoke being wound by a winding and comprising two core-facing surfaces and at least one flux sensor situated on at least one of the two core-facing surfaces; supplying current to the winding to inject magnetic flux into the at least one tooth; using the at least one flux sensor to measure a signal resulting from the injected magnetic flux; and using the measured signal to detect variations in flux on the at least one core-facing surface representative of core faults. A system includes: at least one magnetic yoke for being positioned near at least one tooth of the core and being wound by a winding and comprising two core-facing surfaces; and at least one flux sensor situated on at least one of the two core-facing surfaces.
