Abstract
A model reduction technique based on the proper orthogonal decomposition is applied to a finite-element formulation of the electroquasistatic field equation. The presented formulation takes into account dielectric effects as well as nonlinear conductive effects. The implementation is based on a 2-D axial symmetric model. The applied proper orthogonal decomposition is based on the singular value decomposition. Numerical results are shown for an axial-symmetric high-voltage surge arrester consisting of constant and nonlinear conductive material.Keywords
