1. 1. Finite element modelling of LV transformer winding to simulate dynamic events occurring under short circuit : In Ansys Mechanical

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Madhu Venkata Sri Prudhvi Bikkina; [2020]
   Keywords : Ansys Mechanical; LV winding; Power Transformer; Short-circuit; Spiraling; Torsional Mode Shapes;

   Abstract : The ability to withstand a short circuit is the most essential feature of a power transformer. The most important reason to design short-circuits proof transformers is to ensure the reliability of the power grid (avoiding black outs etc.) and safety (fire and explosion in case of failure).

3. 2. Performance Analysis of Unskewed Asymmetrical Rotor for LV Induction Motors

   University essay from KTH/Elektrisk energiomvandling

   Author : Usman Shaukat; [2012]
   Keywords : Induction motor; skewed rotor; inter-bar currents; starting performance; asymmetrical rotor slots; 2D FEM; synchronous torques.;

   Abstract : This master thesis presents a comparative analysis of the starting performance and losses at rated operation for a 15 kW, 4-pole industrial induction motor, mounted with standard skewed, unskewed and unskewed asymmetrical die-cast aluminium rotors through measurements and simulations. It is a well-known fact that rotor skewing suppresses the synchronous torques at low speeds and also reduces the audible noise of the machine. READ MORE
