    Keywords : Dielectric frequency response; End corona protection; Finite element method; High voltage rotating machines; Stator insulation; Dielektrisk frekvensrespons; Ändglimmskydd; Finita element metoden; Högspänningsmaskiner; Statorisolering;

    Abstract : High Voltage (HV) rotating machines are widely used in power generation and heavy industry companies. Silicon Carbide (SiC) material is used in the stress grading structure of HV electric machines because of its non-linear characteristic. READ MORE

  3. 2. Dielectric Response and Partial Discharge Characteristics of Stator Winding Insulation System with SiC Stress Grading

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

    Author : Amar Abideen; [2020]
    Keywords : Stator Insulation; Dielectric Frequency Response; Polarization Depolarization Current; Insulation Modelling; FEM simulation;

    Abstract : The typical construction of a stator coil includes the use of end corona protection (ECP)coating, which is made of semi-conductive materials like silicon carbide (SiC). Thepurpose of ECP is to smooth the electric stress distribution near the slot exit, limitingthe electric field and partial discharge (PD) activity within the insulation system. READ MORE
