Abstract
High voltage insulation systems play a crucial role in prolonging the life of stator bars. However, due to manufacturing defects and through normal operations, gas-filled cavities can appear. Partial discharges within these cavities compromise the integrity of the insulation and can have an adverse impact on the life of the insulation. The purpose of this thesis is to investigate cavities in stator bars with different characteristics, such as, the shape, size and location of the cavity in the insulation. Through the use of Finite Element Analysis (FEA) software, the thesis examines how these three physical properties impact the electric field through the cavity. This includes the effect that each of these parameters has on one another. An additional numerical approach will be explored to determine a critical cavity size at which partial discharges will not occur or will not have detrimental effects on the life of the insulation system, which is dependent on the applied voltage on the stator bar.
