摘要
The rapid increase in both voltage level and capability of HVDC power transmission and transformation equipment poses great challenges to both integration and reliability of power grids.The insulation systems deployed along with these equipments have to withstand the severe electric field distortion,higher temperature rise and greater mechanical stress,etc.Advanced insulation materials with unique comprehensive performance provide effective solutions to meet new requirements.Indeed,investigating the dielectric properties,determining the failure mechanisms,and exploring novel insulation materials become the core issues in developing more capable insulation systems.
