  • Experimental Investigation on Unipolar Ion Flows

    The amount of available experimental data concerning corona originated space- charge flows is large; however, there is a persistent need for exploring the still overlooked or underestimated supplementary performances. These can emerge from special ion-flow field structures and can be monitored while changing pivotal geometrical parameters one at a time. Owing to the informative character of some individual sources, a demanding experimental strategy has been adopted for making the investigation on unipolar ion flows as complete as possible. A number of sources have been categorized, in this chapter, in function of the injection system and methodically monitored. Therefore, a suspended electrode becomes a V-shaped wire, a two-conductor bundle, an inclined rod, a partially sheathed wire, a pointed-pole sphere and a straight wedge. A 3D generalization of the experimentally discovered performances is given in light of the deep connection between the acknowledged general character of the homeomorphism and the notion of invariance.

  • Ion-Flow Models: A Review

    Modeling a unipolar ion flow is a difficult task that has been shared by a number of researchers in the past century. This chapter is presented as a cursory survey of the available studies on the unipolar ion flow. Deutsch established three hypotheses, some of which are applicable under specialized conditions, regarding the unipolar ion flow in the wire-plane gap. The chapter describes some unipolar flow field problems before discussing special models namely, drift of charged spherical clouds and a method based on a simple geometrical construction describing the asymptotic ion flow for a rod-plane configuration. Estimating the Deutsch hypothesis (DH) validity is an exercise still under way and that the involved investigations persist to contradict each other.

  • Methods of HighPower Electromagnetics

    High-power electromagnetics (HPE) treats the common characteristics of those areas of electromagnetics that require consideration of nonlinear processes in the generation or coupling of the HPE fields. Predictions of HPE processes normally require simultaneous solution of Maxwell's equations and equations governing the behavior of the air or other gas in breakdown conditions. That breakdown is in response to the local fields in the air, and can be enhanced by geometry. Common sources of these high fields include lightning, electromagnetic pulse and related phenomena, high-power microwave sources, and other discharges, including electrostatic discharge (ESD). The discharges may take the form of a corona or a long spark. They may be enhanced by local ionizing conditions, like those caused by a nuclear explosion or within a thundercloud. This paper will review the basic concepts and applications of HPE and present some examples.

  • Applications to Lightning Surge Protection Studies

    This chapter reviews representative applications of the finite-difference time domain method (FDTD) method to lightning electromagnetic pulse and surge simulations. The applications reviewed include lightning electromagnetic fields at close and far distances, lightning surges on overhead power transmission line (TL) conductors and towers, lightning surges on overhead distribution and telecommunication lines, the lightning electromagnetic environment in power substations, and lightning surges in wind-turbine- generator towers. It also includes lightning surges in photovoltaic arrays, the lightning electromagnetic environment in electric vehicles, the lightning electromagnetic environment in airborne vehicles, lightning surges and electromagnetic environment in buildings, and surges on grounding electrodes. When an overhead ground wire of a TL is struck by lightning, corona discharge will occur on this wire. Corona discharge around the ground wire reduces its characteristic impedance and increases the coupling between the ground wire and phase conductors.
