“…Therefore, small particles can carry a larger amount of charge than that is normally expected. There have been several theoretical predictions (Harper, 1967, Pedersen, 1967, Elghazaly and Castle, 1987, Pedersen, 1989, Crowley, 1991, Nakajima and Sato, 1999a for the maximum charge of spherical solid particles sustainable in normal air. Fig.15 shows them with the Rayleigh fission data for glycerol droplets in normal air in a bold broken line.…”

“…Fig.15 shows them with the Rayleigh fission data for glycerol droplets in normal air in a bold broken line. The papers by Pedersen (1967Pedersen ( , 1989 did not actually refer to the breakdown around a charged isolated particle. The curves labeled "Pedersen" in Fig.15 were calculated by the author and his colleague (Nakajima and Sato, 1999a,b) after Pedersen's novel work.…”

“…Many empirical formulae are available from which breakdown or corona onset field strengths may be calculated. Such formulae are, however, valid only within certain ranges, and extrapolation can lead to large errors [6], [7]. In this order, this paper proposes a new technique for the analysis and study of gas discharge (breakdown and discharge steps in air).…”

-The objective of this paper is to study the discharge phenomenon for a point-plane air interval using an original fuzzy logic system. Firstly, a physical model based on streamer theory with consideration of the space charge fields due to electrons and positive ions is proposed. To test this model we have calculated the breakdown threshold voltage for a point-plane air interval. The same model is used to determine the discharge steps for different configurations as an inference data base. Secondly, using results obtained by the numerical simulation of the previous model, we have introduced the fuzzy logic technique to predict the breakdown threshold voltage of the same configurations used in the numerical model and make estimation on the insulating state of the air interval. From the comparison of obtained results, we can conclude that they are in accordance with the experimental ones obtained for breakdown discharges in different point-plane air gaps collected from the literature. The proposed study using fuzzy logic technique shows a good performance in the analysis of different discharge steps of the air interval.
