In the lightning impulse test, the 10 kV fusion voltage transformer intelligent component acquisition port often suffers from functional failure or breakdown. In this paper, experimental measurement and inversion calculation were used to study the electromagnetic disturbance level of smart component acquisition port. During the inversion calculation, the applicability of the dual exponential function model, Heidler function model, and impulse function model as the primary source for describing the lightning impulse device were compared and analyzed. The results show that the double exponential model was used as the calculation source of the primary side lightning waveform, and the inversion calculation results were in good agreement with the actual measurement. In addition, the effects of the primary side lightning voltage peak, wave head, and wave tail parameters on the maximum amplitude of the disturbance waveform calculated by inversion are discussed and analyzed. Based on the analysis results, a sufficient inversion calculation parameter was proposed to estimate the disturbance level of the intelligent component acquisition port. Finally, the measured results were compared and discussed with the IEC 61439 assessment level, and it was suggested that the assessment level of fusion equipment should be modified.

“…Existen metodologías desarrolladas en el dominio del tiempo y de la frecuencia que permiten evaluar el campo magnético producido por una descarga eléctrica atmosférica al interior de una estructura apantallada. Entre las metodologías en el dominio de la frecuencia, está la desarrollada por Orlandi et al (1998), que permite evaluar la distribución del campo magnético en el interior de las estructuras y calcular las tensiones inducidas en lazos de conductores en su interior, además hace consideraciones probabilísticas para el análisis de los efectos de los rayos. En el dominio del tiempo se tienen metodologías como la desarrollada por investigadores de la Universidad de Sao Paulo (Sartori et al,2002, Sartori y Orlandi, 2000Sartori, 1999;Sartori et al, 1998;Sartori y Cardoso, 1995;Sartori y Cardoso, 1994) y del Instituto de ingeniería de alta tensión y alta corriente de la universidad tecnológica de Dresden (Smolke y Engelmann,1995), las cuales permiten evaluar los campos magnéticos al interior de estructuras que conducen la corriente del rayo, y hacer otros análisis como la efectividad de apantallamiento de equipos y voltajes inducidos en lazos de conductores.…”

Se presenta una metodología para el cálculo del campo magnético, en el interior de edificaciones con sistemas de protección contra descargas eléctricas atmosféricas (LPS). Los conductores del LPS y el canal de la descarga se consideran haciendo uso del modelo electromagnético hibrido, que parte de las expresiones de Maxwell en el dominio de la frecuencia. Inicialmente, son determinados los acoples inductivos y capacitivos entre los diferentes elementos conductores de LPS, lo que a su vez permite calcular la distribución de la corriente de la descarga en el sistema. Luego, se calcula la intensidad de campo magnético en puntos en el interior de la estructura impactada. Finalmente, se hace la caracterización de la intensidad de campo magnético en superficies dentro de la estructura. Los resultados son comparados con los obtenidos mediante otras metodologías propuestas, demostrándose que la herramienta y la metodología desarrolladas son adecuadas para determinar el campo magnético en el interior de edificaciones con sistemas LPS.

“…Sensitive electronic devices inside buildings might be impaired by lightning, and it is therefore important to be able to predict the expected lightning electromagnetic pulse (LEMP) characteristics in order to design effective lightning protection methodologies on the basis of the concept of lightning protection zones (LPZs) [1]. Traditionally, transmission-line (TL) theory-based simulation techniques have been used to analyze lightning surge phenomena [2][3][4][5]. However, these simulation techniques were developed based on the assumption of transverse electromagnetic (TEM) mode propagation, an assumption that is not straightforwardly applicable for surge analysis in three-dimensional structures such as buildings.…”

The finite‐difference time‐domain method is one of the most widely used numerical electromagnetic computation techniques, and it has become an effective tool for analyzing electromagnetic transient phenomena in three‐dimensional structures and grounding systems. However, the available approaches for representing thin wires apply only to bare conductors such as overhead power lines and earth electrodes. In this work, we demonstrate the applicability of thin‐wire representation techniques to wires surrounded by both lossy and lossless media, such as reinforcing bars inside lossy concrete. The validated technique is then illustrated through the study of a reinforced‐concrete building struck by lightning to evaluate the effect of concrete on the penetration of lightning electromagnetic pulses inside the building. © 2019 Institute of Electrical Engineers of Japan.
