Outline of Final Research Achievements

For the future introduction of HVDC power systems, it is important to establish an electrical insulation techniques in power equipment, such as transformers and switchgears. In this research, through the investigation of HVDC electric field distribution, charge dynamics, charging characteristics, DC-partial disvcharge (PD) and flashover phenomena, their fundamental electrical insulation performances are investigated and established. Firstly, the electric field calculation techniques especially for an application to HVDC system were established, together with those at DC polarity reversal conditions. Next, with the analytical development, the experimantal investigations on DC-PD, DC charging on solid insulators and DC flashover chacteristics were carried out and the mekanisms were clarified. Finally, by summarizing those techniques, fundamental techniques for HVDC electrical insulation were clarified and entablished.
