Abstract :
Internal and surface partial discharges in HVDC apparatus are investigated in this paper focusing on their dependence on humidity and temperature. The experimental observations show that environmental conditions play an important role in the discharge behavior under HVDC. A preliminary effort has been made to explain these phenomena resorting to space charge analysis.
