In a nonuniform field, the positive direct and 60-cycle breakdown voltages of sulfur hexafluoride (SF6) as a function of pressure pass through a pronounced maximum. In the region of this maximum, corona is present at a much lower voltage than the breakdown voltage, and the impulse ratio may be less than one. In fact, the positive impulse, i.e., 1??x40-??sec (microsecond), breakdown voltagemay be only...
Hickam(1) has shown that at extremely low pressures (10−4–10−5 mm) the electron capture curve of SF5 is dependent on the temperature at which the experiment is conducted. Experiments were performed to see if there was a temperature effect on the breakdown of SF5. In non-uniform fields, the positive direct voltage for breakdown in SF5 as a function of pressure goes through a maximum. The reason for...
