- Abstract
In a previous work, a typical case was studied, where a solid sheet insulation contained a void under DC or AC voltage. In the present paper, a more complex case is studied in order to study the charging phenomenon in HVDC valve windings and cables under a superposition of AC and DC voltages. Real inception voltage is calculated, and it agrees with the experimental results previously reported. Moreover, the location of the charging phenomenon is calculated, and it is correlated to the ratio between AC and DC voltage.
