Abstract |
The relationship between the partial discharge and the discoloration of lubricant at the interface of the underground transmission cable outdoor termination analyzed in this paper. The possibility of discoloration of lubricant by partial discharge is firstly verified through simulation test of silicone lubricant discoloration. Then breakdown mechanism is proposed through various analysis such as the viscosity of lubricant, the possibility of partial discharge due to formation of thick circumferential silicone lubricant, and so on. |
