Abstract

The impact of lightning electromagnetic pulses (LEMPs) on cables poses a significant challenge to the reliability and safety of power systems. This study aims to investigate the electromagnetic response and electromagnetic shielding effectiveness (ESE) of multi-layer and single-layer shielded cables against the LEMP. Through time-domain and frequency-domain analyses, the research evaluates how different grounding configurations and shielding methods influence electromagnetic coupling in the cables. The findings indicate that connecting both ends of the shield or metal pipe to the ground offers the most effective protection, greatly minimizing the induced response. Multiple shields offer enhanced performance compared to the single shield configuration, with the ESE increasing from 14.60 dB to 20.03 dB as the number of shields increases. Additionally, increased the metal pipe coverage from 60% to 100% improves the ESE of the cables, reducing the energy coupled to the cable by up to 60%. This study provides valuable insights into effective shielding techniques for LEMP protection in various engineering applications.

期刊介绍： Electric Power Systems Research is an international medium for the publication of original papers concerned with the generation, transmission, distribution and utilization of electrical energy. The journal aims at presenting important results of work in this field, whether in the form of applied research, development of new procedures or components, orginal application of existing knowledge or new designapproaches. The scope of Electric Power Systems Research is broad, encompassing all aspects of electric power systems. The following list of topics is not intended to be exhaustive, but rather to indicate topics that fall within the journal purview. • Generation techniques ranging from advances in conventional electromechanical methods, through nuclear power generation, to renewable energy generation. • Transmission, spanning the broad area from UHV (ac and dc) to network operation and protection, line routing and design. • Substation work: equipment design, protection and control systems. • Distribution techniques, equipment development, and smart grids. • The utilization area from energy efficiency to distributed load levelling techniques. • Systems studies including control techniques, planning, optimization methods, stability, security assessment and insulation coordination.
