Abstract

Presence of Partial Discharges(PD) is a matter of great concern for cable insulation. The behavior of partial discharges is much more complex in DC insulation systems compared to AC ones, particularly in HVDC cables. It is because PD is basically an outcome of electrical stress enhancement under loaded conditions, the temperature distribution, electrical field distribution and occurrence of PDs all become interlinked with each other. Present paper makes an attempt to shed some light on such issues. A method is presented on how to calculate the PD inception voltage in a HVDC cable under load conditions in the presence of a void. The effect of shape and location of the void on the PD inception voltage is also examined.
