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

Setiap tahun, Pemerintah Kota/Kabupaten selalu menyelenggarakan Lomba Kompetensi Siswa (LKS) di bidang teknik listrik antar SMK (Sekolah Menengah Kejuruan) tingkat kota/kabupaten. Kenyataan di lapangan, proses menyerap ilmu dan berlatih dari sekolahan masih kurang maksimal karena terbatasnya waktu. Pelatihan atau pembekalan bagi siswa SMK jurusan teknik listrik, diharapkan dapat memberikan arahan dan kisi-kisi tentang Lomba Kompetensi Siswa (LKS) bidang teknik listrik agar para siswa lebih mantap, percaya diri dengan adanya skill tambahan yang di berikan. Selain itu, dampak dari pembekalan ini adalah agar siswa mendapatkan nilai maksimal dan bisa menjadi pemenang dari lomba LKS ini. Dari pelatihan atau pembekalan tersebut didapatkan hasil yang memuaskan, siswa dapat merakit dengan cepat, benar dan rapi. Siswa juga dapat menjelaskan secara detail apa yang dikerjakan dan bahkan bisa menyelesaikan trouble shooting yang diberikan dengan sempurna.

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%.
