The four key factors are peak current, current steepness, charge, and impulse force. Notably, tropical and subtropical lightning has distinct characteristics. Designing an effective protection system requires considering local parameters. These form the foundation for safeguarding equipment and assessing potential impacts on nearby structures. Analyzing lightning damage and formulating protection strategies heavily relies on understanding lightning peak current.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><div class=\"fullwidth\" ><div class=\"vc_row wpb_row vc_row-fluid vc_custom_1734169162466 vc_row-o-content-bottom vc_row-flex\"><div class=\"wpb_column vc_column_container vc_col-sm-6\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div  class=\"wpb_single_image wpb_content_element vc_align_center wpb_content_element\">\n\t\t\n\t\t<figure class=\"wpb_wrapper vc_figure\">\n\t\t\t<div class=\"vc_single_image-wrapper   vc_box_border_grey\"><img loading=\"lazy\" decoding=\"async\" width=\"426\" height=\"283\" src=\"https:\/\/stei.itb.ac.id\/wp-content\/uploads\/Lightning-strike-in-Lembang-West-Java-Indonesia.jpg\" class=\"vc_single_image-img attachment-full\" alt=\"\" title=\"Lightning strike in Lembang, West Java, Indonesia.\" \/><\/div><figcaption class=\"vc_figure-caption\">Figure 1.

This paper introduces a novel method, the Peak Current Measurement System (PCM), applied in Indonesia, incorporating a Lightning Event Counter (LEC) and Magnetic Tape. The derived information aids decision-making for maintenance of lightning protection systems. By monitoring strike frequency and intensity through the LEC and processing data with Audacity software, authorities can gain insights into performance and vulnerabilities. This proactive approach ensures the safety and reliability of systems facing lightning-related hazards.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><div class=\"fullwidth\" ><div class=\"vc_row wpb_row vc_row-fluid vc_custom_1734169162466 vc_row-o-content-bottom vc_row-flex\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div  class=\"wpb_single_image wpb_content_element vc_align_center wpb_content_element\">\n\t\t\n\t\t<figure class=\"wpb_wrapper vc_figure\">\n\t\t\t<div class=\"vc_single_image-wrapper   vc_box_border_grey\"><img loading=\"lazy\" decoding=\"async\" width=\"611\" height=\"452\" src=\"https:\/\/stei.itb.ac.id\/wp-content\/uploads\/Rogowski-Coil-Performance-Test.jpg\" class=\"vc_single_image-img attachment-full\" alt=\"\" title=\"Rogowski Coil Performance Test\" \/><\/div><figcaption class=\"vc_figure-caption\">Figure 3.
