Abstract

The theory and application of external lightning protection systems for buildings are not included in the curriculum of the Electrical Engineering Department. Instead, this material is introduced to students through skill training outside regular class schedules, with a focus on components of external lightning protection systems such as finials, down conductors, and grounding. The obligation to install lightning protection systems on buildings is mandated by Law No. 28 of 2002 and Government Regulation No. 36 of 2005. Protection from lightning requires precise planning to be effective in safeguarding buildings. Analysis of lightning strike phenomena and their consequences can be conducted by applying theoretical principles, such as electric fields, magnetic fields, induction voltage, and various theorems related to lightning strike phenomena. Students are provided with an understanding of the concept of lightning strikes, the potential dangers, and the damage they can cause to buildings, living beings, and electronic equipment both inside and outside the building that is affected by lightning strikes. In this simulation, each group is given images of buildings with varying roof shapes and sizes. The buildings are equipped with external lightning protection systems, including the number and placement of finials on the roof, which are then simulated. The effectiveness of the finials placed in these locations is tested to analyze the extent of protection, to ensure that the building is protected from the dangers of lightning strikes.  A total of 40 students participated in this activity, divided into 8 groups. Five groups successfully simulated the installation of finials to achieve an effective level of protection against lightning strikes, while the remaining three groups could only determine the extent of the protection area without being able to plan the installation efficiently. This training provides a benefit by enhancing the knowledge and skills of the students. The students' enthusiasm is reflected in active discussions and question-and-answer sessions that contribute to problem-solving.

Abstract

Base Transceiver Station (BTS) towers are highly vulnerable to lightning strikes. A lightning strike is a moving electric charge that generates an electric field and a magnetic field, both of which are vector quantities, and induces voltage around the tower. The closer to the tower, the greater the values of the electric field, magnetic field, and induced voltage generated. A 49-meter highs tower in Mataram City is located 25 and 300 meters from residential areas and public facilities. The metabolism of living organisms, such as blood circulation, nerve function, heart rate, lung function, cell growth, and cell division, are also vector quantities. Exposure of living organisms to external electric fields exceeding the threshold of ≥10 kV/m can disrupt their metabolism. It is crucial to determine the magnitude and direction of the electric field vector caused by lightning strikes on BTS towers and how it affects living organisms around the tower. Observations are based on Coulomb's Law and its derivative theories on electric fields. The peak lightning current in tropical areas ranges from 10 to 100 kA, with a frequency of 200 kHz. The electric field intensity at distances of 25 and 300 meters is 58.30, 584.50, 4.86, and 48.71 kV/m, respectively. These results indicate that a distance of 25 meters from the tower is not safe from exposure to high electric field intensity values.
