Tall-Structure Lightning Return-Stroke Modelling
نویسنده
چکیده
A lightning return-stroke model, based on the lightning return-stroke current derivative measured at the Toronto CN Tower is presented in this paper. A 3-section transmission line representation of the CN Tower along with the derivative of the modified Heidler function is used to simulate the measured current derivative signal. Reflections from major structural discontinuities of the CN Tower as well as reflections from the upward-propagating lightning return-stroke channel front are taken into account in the proposed model. The proposed return-stroke model is experimentally evaluated based on the comparison between the simulated and measured magnetic field.

electromagnetic radiation from lightning return strokes to tall structures
The study of the interaction of lightning electromagnetic fields with electrical systems and the design of appropriate protection strategies are generally based on statistical distributions of the lightning current measured at the channel base using either instrumented towers or artificial initiation of lightning using rockets. Recent studies based both on numerical modeling and experimental ob...
متن کاملDetermination of lightning currents from far electromagnetic fields: Effect of a strike object
We discuss in this paper the influence of the presence of an elevated strike object on the peak of the lightning return stroke current determined from remote field measurements. We develop analytical expressions relating the lightning return stroke channel-base current and the far electromagnetic field for different specific cases, namely, (1) ground-initiated return strokes (classical transmis...
متن کاملCN Tower Lightning Return-Stroke Current Simulation
Different functions have been used to model the lightning return-stroke current with the aid of direct current measurements at tall structures. In this paper, a comparison between the Pulse function and Heilder function is carried out to find out the suitability of each of these functions for simulating the lightning return-stroke current, measured at the CN Tower. An automated system for deter...
متن کاملOn the use of lumped sources in lightning return stroke models
[1] We consider the use of lumped voltage and current sources in engineering lightning return stroke models with emphasis on those including a tall strike object. If the model is to be used for computing remote electric and magnetic fields, we suggest a representation of the lightning channel as a transmission line energized by a lumped voltage source, with the voltage magnitude being expressed...
متن کاملElectromagnetic Field Due to Lightning Strikes to Mountainous Ground
The produced electric and magnetic fields due to lightning strikes to mountainous ground are determined in this paper. For the sake of simplicity a cone-shaped ground with finite conductivity is assumed to represent a natural nonflat ground. By this assumption, we deal with an axillary symmetrical structure so we use the cylindrical 2D-FDTD to save the simulation memory and time, dramatically. ...
