Electric Field Optimization of Epoxy-Based Spacer with Surface Conductivity Gradient Material (,-SFGepoxy-based spacer in high voltage direct current gas insulated transmission lines (HVDC GIL). Based on the ±500 kV HVDC GIL model, the iterative method is applied to optimize the thickness gradients of the σ-SFGM layers on convex and concave surfaces of the basin-type spacer. It is proved that the

Parameter Design of Multi-dimensional Functionally Graded Materials (,/,-MFGM) for Epoxy-Based Spacelines and switchgears (HVDC GIL/GIS). The effects of surface conductance graded materials (.-SFGM) and bulk permittivity graded materials (.-FGM) on the electric field distributions along the basin-type spacer are investigated under DC stationary and transient conditions. Results show that the .-SFG

Results show that gas density together with the dielectric strength around the upper post is reduced over 11% under gas convection generated by the load current. The greater temperature gradient (29 K) along the lower post accelerates more surface char

Reconstructing Fully-Rigged Characterssurface charge distorts the local electric field and leads to surface flashover faults in extreme situations. As a result, it is important to figure out the mechanism of surface charge accumulation process. In this chapter, a simulation model combining both the plasma hydrodynamics and charge trappi
