Lightning Electromagnetic Fields at Very Close Distances Associated with Lightning Strikes to the Gaisberg Tower

Marcos Rubinstein, Davide Pavanello, Pierre Zweiacker, Abdolhamid Shoory, Seyed Abbas Mosaddeghi

In this paper we present and discuss measurements of electric (vertical and radial) and magnetic fields from leaders and return strokes associated with lightning strikes to the 100 m tall Gaisberg tower in Austria obtained in 2007 and 2008. The fields were ...

On the Relationship Between the Signature of Close Electric Field and the Equivalent Corona Current in Lightning Return Stroke Models

Carlo Alberto Nucci

Engineering return stroke models can be categorized either as current generation (traveling current source type) models or current propagation (transmission line type) models. The current generation models are described among other parameters by a corona c ...

On the use of the equal area rule for the wire-grid representation of metallic surfaces

Marcos Rubinstein, Abraham Rubinstein

This paper presents a brief theoretical discussion on the issue of the wire-grid representation of surfaces using the Numerical Electromagnetics Code (NEC). Different approaches for the determination of the parameters (in particular, the segment radii) of ...

DC performance, AC loss and transient field stability of five medium size NbTi cable-in-conduit conductors with parametric variations

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche, Martin Vogel

Five medium size NbTi cable-in-conduit conductors with parametric variations in the cable layout were fabricated of three different strands to investigate their DC performance, AC loss behaviour and transient stability by means of the SULTAN facility. A co ...
