Sensitivity Analysis Based New Numerical Approach with Green Function for Optimization

In this study, sensitivity analysis based on a new numerical approach is developed for the three-dimensional structural optimization of high voltage system devices. It has been developed using Green’s theorem in a closed form to satisfy all boundary conditions and necessary conditions, including material and geometric dimensions. The developed sensitivity function and objective function are suitable for structural optimization of all electrostatic problems. The suitability and application of the developed function were made on the bushing. The changing geometry information was obtained from the developed sensitivity function as a result of the optimization. The analysis made with the classical design and the developed function were compared with each other. Optimization with the developed function has provided insulation and conductor size reduction. Experimental test devices before and after optimization process produced and tested. These results are presented in the study.
