Accurate tower models for fast transients are essential for the insulation design of overhead lines, since lightning may produce temporary or even permanent faults. The aim of the work is to further investigate the nature of the electromagnetic modes supported by the tower, and on the applicability of the transmission line approaches, originally inspired by the model proposed by Jordan. The influence of a perfectly conducting ground plane and of losses distributed along the tower will be discussed. A new approach, based on the Sommerfeld-Goubau wave formalism, is proposed to give physical insights on the propagation phenomenon along transmission line towers.

塔的瞬态分析：基于 Sommerfeld-Goubau 波的修正理论

用于快速瞬变的准确塔模型对于架空线路的绝缘设计至关重要，因为闪电可能会产生暂时甚至永久性故障。这项工作的目的是进一步研究塔支持的电磁模式的性质，以及传输线方法的适用性，最初受到约旦提出的模型的启发。将讨论完美导电接地平面和沿塔分布的损耗的影响。提出了一种基于 Sommerfeld-Goubau 波形式的新方法，以对沿传输线塔的传播现象提供物理见解。
