Abstract

Load Break Switch adalah salah satu peralatan yang mengambil peran dalam sistem distribusi tenaga listrik yang berfungsi sebagai pembatas antar section. Salah satu bagian penting dari Load Break Switch adalah isolatornya, dimana fungsi isolator disini untuk mengisolasi tegangan pada kawat penghantar agar tidak mengalir pada tiang distribusi. Isolator juga bertugas menahan medan listrik yang mengalir agar tidak terjadi distribusi medan listrik berlebihan yang dapat membahayakan makhluk hidup dan peralatan lain di sekitar tiang distribusi. Pada aplikasinya di lapangan, terdapat berbagai jenis kontaminan yang ada dan dapat mempengaruhi kemampuan dielektrik isolator Load Break Switch apabila menempel pada permukaannya. Oleh dari itu diperlukan analisa pengaruh kontaminan terhadap distribusi medan listriknya. Pada tugas akhir ini, telah dilakukan analisa distribusi medan listrik pada Load Break Switch yang difokuskan pada bagian isolator menggunakan simulasi berbasis Finite Element Method. Analisa ini meliputi perbandingan medan listrik pada permukaan isolator, antara kondisi normal terhadap kondisi terkontaminasi air laut dan kondisi normal terhadap kondisi terkontaminasi debu. Dengan medan tertinggi saat kondisi isolator terkontaminasi air laut berturut-turut dengan kondisi terkontaminasi debu sebesar 266 kV/m dan 162 kV/m sedangkan saat kondisi normal sebesar 162 kV/m.=====Load Break Switch is one of many electrical instruments that take part in low voltage electricity distribution networks which is suitable for switching operations and its commonly used as a sectionalizer. It is necessary to pay attention to its insulator which used to isolate the voltage at the phase line so it will not flow to the distribution tower. Insulators act to resist the ongoing large amount of electrical field that will endanger living things and other instruments around the distribution tower. In its application, there are several types of contaminants that will affect its dielectric strength. So, an analysis of contaminant influence upon its electrical field is critically needed. In this study, had been done an analysis on its electrical field distribution focused on its insulator using a Finite Element Method. This analysis contains of electrical field comparison on Load Break Switch insulator surface, between insulator in normal condition towards seawater drops contaminated and normal condition towards sandy soil contaminated. And the highest point of electrical field consecutively in seawater contaminated and sandy soil contaminated in the value of 266 kV/m and 162 kV/m, meanwhile the value of its electrical field in normal condition in the value of 162 kV/m.
