Abstract

In meeting consumers' needs for electric power continuously, the reliability of electric power distribution is something that needs to be considered. One of the reliability parameters is the network's ability to distribute power from generators continuously, with the allowable voltage and frequency quality. For this reason, the presence of an insulator in the power distribution system is very important considering its function is to separate live conductors from their supports. If the isolation properties do not function, a voltage failure will occur so that power distribution will stop, resulting in low system reliability. From the data from the calculation results of 150 kV high voltage overhead line power losses due to flashovers on insulators installed in each fouling area, it is clear that increasing the contaminant value will make it easier for flashovers to occur which cause very large power losses and conversely, insulators that are clean make it difficult. the occurrence of flashover so as to reduce power losses on the transmission line. The appropriate insulator to use is the fog type, because the diameter is wider, increasing the propagation distance so that the insulator's ability to withstand greater voltage

Abstract

Pengabdian ini berfokus pada pembuatan Alat Semprot Otomatis dengan Sensor Cahaya untuk mencegah kucing liar memasuki Taman Toga Sehat di Desa Asrikaton, Pakis, Malang. Tujuan utama kegiatan ini adalah menciptakan teknologi yang ramah lingkungan untuk menjaga kebersihan taman dari kotoran kucing liar tanpa menyakiti hewan tersebut.Metode pelaksanaan meliputi survei lokasi, perancangan alat, pemasangan sensor gerakan yang mengaktifkan semprotan air otomatis, dan edukasi kepada warga tentang cara penggunaan serta perawatan alat. Hasil pengabdian menunjukkan bahwa alat berhasil dipasang, namun masih diperlukan penyesuaian pada sensitivitas sensor agar hanya mendeteksi kucing, bukan manusia. Teknologi ini berpotensi meningkatkan kebersihan taman dan memberikan solusi yang efektif untuk masalah kotoran hewan liar.

Abstract

The dangers arising from the 500 kV extra high voltage overhead lines to the surrounding environment can actually be minimized in several ways. One of the methods is to change the configuration of the conductor arrangement. Based on the laws in field theory which state that the magnitude of the field quantity on a charged conductor can differ depending on the distance, area, or volume, an analysis was carried out to understand the effect of the phase arrangement on the electric field intensity under the 500 kV overhead transmission line. The Finite Difference Method uses a numerical approximation to the partial derivative of the differential equation describing the electric field. The use of the Hybrid Tower combines vertical and horizontal designs to achieve a balance between low electric fields and land efficiency. Of the 36 combinations of phase arrangements on transmission lines with a double-circuit vertical configuration, there is a large variation in the resulting field intensity. Information on the phase arrangement that produces the smallest field intensity is very important. The arrangement of 36 (arrangement T1-S1-R1: T2-S2-R2) produces the lowest electric field intensity. Compared with the super bundle arrangement (arrangement R1-S1-T1: R2-S2-T2), there is a decrease in field intensity of up to 45.842%, while compared with the low reactance arrangement (arrangement R1-S1-T1: T2-S2-R2), there is a decrease in field intensity of up to 33.374%.
