Abstract
A new family of perfluorinated fluids recently has become available. These fluids contain oxygen, in addition to fluorine and carbon. Since these perfluoro polyethers represent potentially interesting electric insulation fluids, their behavior under electrical pulse conditions has been investigated. The results of this study are reported here. Under the prevailing nonuniform field conditions it was noted that the breakdown voltage was lower when the needle was a cathode than when it was an anode. The streamer structures and their inception voltages were studied in some detail. The effect of pressure on the streamer structure was also evaluated and the results are presented here.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
