1. Insulation diagnostics of stator bars
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Insulation in rotating machines is a common cause for failure. Therefore, research in the area is large and is important to further increase the knowledge of the phenomena related to insulation degradation. READ MORE

2. Dielectric Response of SiC-based Stress Grading Material Used in Electrical Machines
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)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. Thermomechanical stress analysis of the main insulation system of traction electrical machines
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : More efficiency heavy-duty vehicles are developed with higher range, updated electronic and mechanical parts. The fuel efficiency and pollution of carbon dioxide need to be lower to achieve new EU regulations. The global population increases with an increased number of heavy-duty vehicles. This, in turn, increases the emission. READ MORE

4. 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)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

5. Real-time detection of stator resistance unbalances in three phase drives
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : 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. READ MORE
