Measurement method for measurement of inductance in magnetic flux density or magnetic saturation in inductive element, involves rectifying measurement current and detecting measurement signal corresponding to rectified measurement current

摘要

The measurement method involves generating a periodically changing measurement voltage across a measuring coil (4), where a measurement current is formed, which is proportional to the current through the measuring coil. The measurement current is rectified and a measurement signal corresponding to the rectified measurement current is detected. A measuring core (3) is provided with another measuring coil, with which a measurement flow is generated, which is superimposed on a section of main flow. An independent claim is included for a measuring device for the measurement of inductance in a magnetic flux density or a magnetic saturation in an inductive element.
