Abstract :
The special geographical circumstance and climate in the plateau will result in the decrease of insulation capability of HV equipment. Thus the weakness of the insulation system may cause insulation invalidation. In this paper, a partial discharge (PD) on-line monitoring system fitting for the plateau area has been developed, based on the study of PD characteristics. After the PD eigenvalues are modified by altitude, the system can be applied for HV equipment on a different altitude. Considering the requirement of an unattended mode, the system can communicate with a remote control center
