Method for measuring inductance during measurement of magnetic flux density or magnetic saturation in e.g. inductive element, involves determining frequency of measurement voltage as measure of measured inductance

摘要

The method involves generating a changing measurement voltage across a measurement winding (4) that is provided in a measuring core (3) by applying a direct current supply voltage to the measurement winding. A current resulting through the measurement voltage is measured. A polarity of the direct current supply voltage is reversed when absolute value of current exceeds a predetermined current limit value. A frequency of measurement voltage is determined as a measure of measured inductance. An independent claim is also included for a measuring device for measuring inductance during measurement of magnetic flux density or magnetic saturation in an inductive element.
