“…Variasi tersebut tergantung pada kedalaman batang elektroda dengan parameter kelembaban, perubahan suhu, kadar garam tanah, dan nilai resistivitas tanah lebih kecil di bawah permukaan permukaan air tanah [4], [9]. Hal tersebut terkait dengan tujuan grounding yaitu dapat secepatnya mendistribusikan arus berlebih ke dalam tanah [10]. Karakteristik tanah berhubungan dengan nilai resistivitas tanah dan pengukuran tahanan pentanahan.…”

Axle counter merupakan peralatan pendeteksi kereta api dengan memancarkan frekuensi gelombang untuk menghitung jumlah gandar pada sarana yang melewatinya. Pada Resort Sintel 4. 1 Tegal sering terjadi kerusakan axle counter karena imbas petir yang mengakibatkan kerusakan komponen pada axle counter. Pada prinsipnya arus berlebih tersebut dapat langsung dibumikan tanpa merusak komponen dengan sistem grounding yang baik. Dengan latar belakang tersebut peneliti merencanakan sistem grounding yang baik untuk mengantisipasi kejadian tersebut. Perencanaan yang dilakukan dengan memperhitungkan kebutuhan grounding dengan metode seri dan paralel, dengan parameter jenis tanah, kedalaman, dan diameter grounding sehingga dapat direncanakan nilai tahanan pentanahan yang sesuai. Peneliti juga mendesain sistem grounding menggunakan software Aspix yang dapat disimulasikan menyerupai kondisi yang sama pada lapangan. Pengukuran langsung nilai tahanan pentanahan diperlukan untuk memvalidasi hasil perhitungan perencanaan dan simulai desain grounding untuk mengetahui faktor kesalahan dari perencanaan yang dilakukan peneliti. Hasil dari penelitian ini adalah sistem grounding berpengaruh pada nilai tahanan pentanahan. Sistem paralel memiliki nilai tahanan pentanahan paling kecil terdapat pada tanah sawah dengan kedalamanan 2,5 meter dan diameter 25mm2. Jadi untuk menentukan nilai tahanan pentanahan yang sesuai, kedalaman penanaman berpengaruh terhadap sistem grounding yang digunakan karena semakin dalam penanaman maka akan semakin mendekati air tanah. Sistem grounding yang efektif untuk sistem seri pada kedalaman 1 meter dengan jenis tanah sawah.

“…The electric field observed at the same point as Condition 2 is almost the same as that computed for Condition 2 (1 MV/m). Figure 9 shows magnitudes of current at representative four points (B, D, E, and G) computed for eight conditions (1)(2)(3)(4)(5)(6)(7)(8) at the moment of at 30 μs. Figure 10 shows magnitudes of electric field at the center of the insulation wall computed for eight conditions (1)(2)(3)(4)(5)(6)(7)(8) at the moment of 30 μs.…”

“…This system is designed to guide all the lightning current to deeper parts of the ground. Therefore, a significant voltage is generated across the insulation layer of the insulated grounding conductor when a fast front lightning current is injected, and it might fatally damage the insulation layer [4,5]. On the other hand, in the proposed system, lightning currents will flow in both a structure to be protected and down conductors, which enclose the structure and are connected to a large grounding ring electrode.…”

Parallel down conductors, which are connected with a lightning rod at the top and a grounding ring electrode (independent of the grounding electrode for internal equipment in a structure) at the bottom, are sometimes installed outside the structure to be protected. This system was proposed and named Surge Sheltering Perfection System (SSPS). In order to enhance its performance, an insulating layer or wall is installed to a depth of 1 m or so in the ground between the grounding electrode for internal equipment to be protected and the grounding ring electrode for down conductors. In this paper, the performance of this enhanced lightning protection system is examined using the finite-difference time-domain (FDTD) method, and its effectiveness is shown.

“…This led to the preference for bare core (BC) as the conductor cable while copper-coated stainless steel was used for the electrode rod. It is also important to note that the effectiveness of grounding system can be influenced by the depth of electrode rod installation and the type of soil [6].…”

Axle counter is a railway detection equipment producing wave frequencies to count the number of axles passing over the track. The existence of a mismatch between the initial and final count numbers usually leads to a red signal and this can prevent the formation of a travel route. The components of axle counter are often damaged by lightning strikes both directly and through the distribution of excessive currents due to a poor grounding system. However, these excessive currents can be safely grounded without damaging the components through the application of a good grounding system. Therefore, this research aimed to plan an effective grounding system to anticipate the incidents using the Wenner method. Some requirements such as soil type, depth, and electrode rod diameter were used in the process to determine the appropriate resistance value. The design was made based on the simulations that closely resembled real field conditions using Aspix software and grounding resistance values were also measured directly on the field to determine the discrepancies between the planning and actual conditions.
