Abstract
An apparatus for monitoring a magnetic core, wherein the apparatus provides a measurement winding which is magnetically coupled to the magnetic core to be monitored, a comparison inductance which is electrically connected in series with the winding and an electronic processing unit which is designed to determine the saturation behavior of the magnetic core to be monitored. The electronic processing unit is configured to record a first electrical signal occurring at the measurement winding and a second electrical signal occurring at the comparison inductance in response to an electrical measurement signal applied to the measurement winding, and to determine the saturation behavior of the magnetic core to be monitored on the basis of the first and second electrical signals. This makes it possible to easily monitor the saturation behavior of a magnetic core and to reliably detect the occurrence of saturation of the magnetic core.
