A model of corona sheath that surrounds the thin core of the lightning channel has been investigated by using a new space charge function. The lightning channel is modeled by a charged corona sheath that stretches around a highly conductive central core through which the main current flows. The channel core with the negatively charged outer channel sheath forms a strong electric field, with an overall...
The generalized traveling current source return stroke model (GTCS), Cvetic and Stanic [1995] is extended to take into account current reflections occurring at ground and at the upper end of the lightning channel, as well as current attenuation along the channel. The ground reflection factor and the top reflection factor of the current pulses are taken from the extended TCS model, Heidler [2007]....
A generalized lightning traveling current source (GTCS) return stroke model has been used to examine the characteristics of the lightning channel corona sheath surrounding a thin channel core. The return stroke process is modeled with positive charge coming from the channel core discharging negative leader charge in the corona sheath. The corona sheath model that predicts charge motion in the sheath...
Summary form only given. Development of a three-electrode spark gap, intended for use in synthetic circuits, is considered in this paper. Two types of three-electrode gas insulated spark gaps have been tested: one with the third electrode located inside the main electrode, an the other with a separate third electrode. A theoretical model which enables optimal design of the spark gap has been presented...
