KONCAR-Institute-Rotor Winding Fault Detection Sensor - 2

ROTOR WINDING FAULT DETECTION SENSOR RWFDS represents a new concept in rotor winding fault detection. This smart sensor enables detection of inter coil short circuits in rotor excitation winding based on the differential magnetic field measurement method (DMFM) inside the machine air gap. The DMFM method eliminates the contribution of the magnetic field present in the symmetric machine from the measuring signal and in that way the output signal depends only on the magnetic field produced by the fault. By using two magnetic field sensors embedded on the stator, inside the machine air gap,...
