Abstract
Results are presented of the aging performance of HVDC line porcelain insulators and related influential factors such as body current and electric-field intensity. The residual dielectric strengths of porcelain materials with different aging times have been measured, and the energy spectrum of aged insulators has been examined. The influence of space charge on field distribution is analyzed
