Examines electrostatic simulations used to analyse insulation stresses and dielectric performance.
This lesson explores electrostatic simulations used to analyse electric field distribution inside transformer insulation systems. Participants learn how FEM models can evaluate dielectric stresses, shielding arrangements, and capacitance behaviour in transformer structures. We will explain how high electric fields can concentrate around sharp edges and floating conductors, potentially leading to insulation failure. Techniques for mesh refinement and field visualization are demonstrated to ensure accurate modelling results. The session highlights how electrostatic simulations support insulation design, risk assessment, and safety margins in high-voltage transformers. Case study examples will be carried out in the FEMM software.
