A theoretical approach to the optimization of high‐voltage insulators

Jesús Ángel Gomollón García, Hermann Singer

The paper first discusses the question of which objectives may be meaningful for the optimization of high‐voltage insulators, and exhaustively analyses the relationship between…

Radiation of pulsed dipole antennas

Pierre Hillion

Using the Jefimenko generalization of the Biot‐Savart law and the Laplace transform we analyse the electromagnetic radiation of a vertical dipole antenna fed with a pulsed…

DOTIG4, a time‐domain numerical code for the study of the interaction of electromagnetic pulses with arbitrary conducting surfaces

Jesús Fornieles Callejón, Alfonso Salinas, Rafael Gómez Martín

This paper describes a computer program DOTIG4, for the study in the time domain, of the interaction of transient electromagnetic pulses (EMP) with arbitrary perfect conducting…

A new transmission‐line model for time‐domain implementation

D.J. Wilcox, M. Condon

The paper presents a new method of solving the Telegraphers’ equations, resulting in a transmission‐line model based on natural modes of oscillation. By means of eigenvalue…

Rapid reswitching of induction machine from current source inverter on the supply net

Jan Rusek

The contribution deals with the dynamics of induction machine during reswitching process from the main feeder on the stand‐by one. The main feeder may be a current source inverter…

Influence of motor and converter non‐linearities on dynamic properties of DC drive with field weakening range

Jan Deskur, Tadeusz Kaczmarek, Krzysztof Zawirski

Improvement of the dynamic properties of DC drive in the field weakening range was the aim of investigation. The non‐linear model of the drive system was applied. In the paper…
