Streamer initiation has been studied in cyclohexane, Midel 7131 (ester based dielectric liquid) and Nytro 10X (mineral transformer oil). Experiments were conducted in point-plane geometry under 40 ns/740 /spl mu/s impulse voltage. The tip electrode was electrochemically etched to approximately 2.0 /spl mu/m, the electrode gap was approximately 18 mm. A(More)
Electrostatic induced coalescence between water drops in stagnant water-in-oil emulsions was studied with a high-speed optical technique. Long range microscope optics was used, and up to four second long sequences of 1000 frames per second were recorded. Emulsions were made of distilled water and naphtenic oil, and prepared both with and without chemical(More)
