Numerical analysis on space charge and AC-DC combined breakdown strength in polyethylene [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation, 2019 In high voltage direct current (HVDC) power transmission systems, electrical equipment at the valve side usually withstands complex stresses like AC-DC combined voltages. Understanding the charge migration and accumulation characteristics under complex stresses and their influences on the breakdown strength are of great significance.
