Experimental Investigation in the Influence of Humidity on Flashover Behaviour of Some Typical Electrodes under D.C.Voltage |
| |
| Abstract: | This paper presents some important results. The teste were carried out under various humidity in the state of nature, and the flashover characteristic for some typical external insulation have been also obtained under D·C·volt-tage·The varying range of humi-ity is from 3·5 to 22g/m3, the D·C·voltage is up to 900kV·Thesed insulation structures include post insulators, suspended insuiator strings, rod-rod air gaps and rod-plate air gaps.The conclusions obtained from tests are valuable for making and modifying relevant testing standards and for HVDC designers. |
