   Sammanfattning : An estimated 30% of the faults in Induction Machine (IM) are related to its stator. These faults are mostly in the form of an Inter-Turn Short Circuit (ITSC) fault i.e., when two winding inside the stator of IM are shorted due to insulation failure. LÄS MER

3. 2. Detection of stator interturn fault of synchronous machine by rotor current analysis : A SIMULATION APPROACH

   Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

   Sammanfattning : One of the major electrical faults of synchronous machines is an interturn short circuit in the stator winding, due to winding insulation failure. A synchronous machine is designed to have electrical and mechanical symmetry in the stator and rotor. LÄS MER
