The authors propose a hybrid method, which is a combination between the Simpson method and finite-difference time domain (FDTD) method for evaluating the electromagnetic field radiated by lightning. The proposed method is an alternative approach that takes advantage of this combination to calculate, first, the radiated magnetic field with the Simpson method, and, second based partially on the FDTD...
The major aim of our investigations is the computation of the voltages induced by an external transient electromagnetic excitation, especially due to the lightning discharge coupling to overhead transmission line networks. In this paper we propose a hybrid method for evaluating the electromagnetic field radiated by lightning The Agrawal et al. model coupling model will be used in order to analyse...
In this paper we propose a hybrid method for evaluating the electromagnetic field radiated by lightning. The proposed method is a combination between the images method and the finite difference time-domain (FDTD) method. We first calculate the magnetic field with the images method and then; the electric field based partially on the FDTD method. The suitability of this method (hybrid method) is checked...
In this paper, we present some results of investigations carried out in the capture zones of an horizontal lightning conductors in the case of discontinuous earth. The conductor may be situated as well as in the upper or the lower earth part. The capture zones were determined in the case of lightning conductor situated between the high voltage rod and the discontinuity (interface) and also in the...
