Multiframe Schlieren Registration of Spatial Structure of the Leader in Compressed SF6
In the interval of pressure and gap distances, characteristic for SF6 equipment, the reasons of the deviation from the Pashen’s law are connected with changing of the breakdown mechanism from streamer to leader1–4. The analysis of the papers on the leader breakdown shows, that the study of the phenomenon is still at the first stage. For the creation of the sufficient complete picture of the phenomenon and development on its basis of the engineering recommendations the further more detailed study of the leader process is necessary.
