Simulation of Permittivity and Conductivity Graded Materials for HVDC GIL for Different Voltage Forms

Hendrik Hensel, Christoph Joergens, Markus Clemens

Functionally graded materials (FGM) are applied in HVDC gas insulated lines (GIL) to control the electric field within the DC insulation system. In HVDC GIL, FGM with a spatial dis…
