Résumé

This paper reports on both initiation and propagation phases of streamers in natural esters (vegetable oils) for high voltage applications, in a point - plane electrode arrangement under lightning impulse voltage (1.2/50 mu s). Four treated oils (VO1/G, VO2/F, VO3/E and VO4/H) and three untreated oils (natural ester for nutrition) extracted from grape seeds (GS), sunflower (SF) and rape seed (RS) are investigated. A synthetic ester (SE1/D) is also tested for comparison. It's shown that the streamers are filamentary in the different tested oils whatever the polarity. For a given voltage, the stopping lengths (L(f)) and velocities of streamers are generally close enough whatever the kind of oil. The values of L(f) as well as the velocities are more important with a positive point than with a negative one. In the view point of stopping lengths and velocities of streamers, there is no difference between treated and untreated vegetable oils.
