  1. 1. Condition monitoring of induction machines using a signal injection technique

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sathiya Lingam Senthil Kumar; [2020]
    Keywords : Condition monitoring; fault detection; fault diagnosis; stator winding fault; inter-turn fault.; Tillståndsövervakning; feldetektering; feldiagnos; statorlindningsfel; kortslutning mellan varv.;

    Abstract : Condition monitoring techniques can be employed to enhance reliability of electric machinery. The stator winding fault is one of the dominant causes for the failure of induction machines. In this work, the condition monitoring of an inverter-fed induction machine using high-frequency signal injection based technique is investigated. READ MORE

  3. 2. Finite-element analysis of an induction motor with inter-turn short-circuit faults

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Hareesh Babu; [2020]
    Keywords : Finite element analysis; stator winding fault; inter-turn short circuit.; Finit-element analys; statorlindningsfel; kortslutning mellan varv.;

    Abstract : Stator inter-turn short circuit (ITSC) faults are one of the common sources for induction machine failure affecting their reliable operation. In this thesis, a finite element (FE) model is developed to study the ITSC fault. The FE model is developed for a prototype induction machine that has the potential to emulate an ITSC fault in the stator. READ MORE

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

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Ata-E Rabbi; [2016]
    Keywords : Synchronous machine; interturn fault; stator fault; rotor current; harmonic current; generator protection; motor protection; inductance matrix.; synkronmaskin; varvfel; statorström; rotorström; strömöverton;

    Abstract : 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. READ MORE
