A non-linear programming approach for the design of controlled-field multi-layer insulation system

A novel method to implement an optimum design of multi-layer insulation systems with embedded conducting strips is presented. These systems are recommended for the insulation of equipment operating at high voltages. The proposed method is based on the study of the orientation of the electric field inside the insulation system. The aim is to approach isotropic characteristics and a higher withstand voltage of the insulation system. Optimum values of the system parameters including the width and spacing of the conducting strips as well as the thickness of the insulating layer are obtained through maximising the electric field component in a certain direction to favor a higher withstand voltage of the insulation system. Utilizing optimization techniques and packages yields a design criteria for these insulation systems. GAMS/CONOPT non-linear optimization solver was used in this work
