![]() This calculates the breakdown voltages in arbitrary electrode configurations and under standard voltage waveforms. This thesis submitted to the Swiss Federal Institute of Technology ETH in Zurich examines the use of sulphur hexafluoride (SF based on the stepped leader model is described. With this, further gases can be characterized for usage as high voltage insulation mediaĮnergy Technology Data Exchange (ETDEWEB) Thus, the thesis provides a method for the prediction of breakdown voltages of arbitrary field configurations under standard voltage waveforms for gases with electron-attaching properties. A model for SF_6 based on the stepped leader model is described. The search for new insulation gases using classical breakdown experiments is discussed. However, the gas also has a very high global warming potential and the content of SF_6 in the atmosphere is constantly increasing. Due to its superior insulation properties, SF_6 is widely used in gas- insulated switchgear. This thesis submitted to the Swiss Federal Institute of Technology ETH in Zurich examines the use of sulphur hexafluoride (SF_6) and similar gases as important insulation media for high voltage equipment.
