  • Publication number: 20170123007
    Abstract: An apparatus for detecting interturn faults inside a rotor winding of a rotating electrical machine with a measuring device. The measuring device has at least two measuring coils oriented differently in space such that, in the case of a measuring device oriented with respect to the rotor winding, a voltage is induced inside the first measuring coil by a first directional component of the magnetic flux density B of the rotating electrical machine and a different voltage is induced inside the further measuring coil by a further directional component of this magnetic flux density B, which directional component differs from the first directional component. The at least two measuring coils oriented differently in space are arranged together on a head part of the measuring device, where interturn faults present on the rotor winding are detected based on temporal voltage profiles of the voltages induced in the two measuring coils.
