Lestari, Pegy (2018) Pengaruh Lokasi Pita Konduksi Terhadap Tingkat Arus Bocor Isolator Silicone Rubber. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini membahas tentang hasil pengujian pengaruh lokasi pita konduksi terhadap arus bocor yang mengalir pada isolator silicone rubber dengan susunan elektroda plat-plat. Untuk menyamakan kondisi di lapangan, digunakan sebuah pengotor yang berupa larutan natrium klorida untuk merepresentasikan zat polutan yang menempel pada isolator silicone rubber. Pada penelitian ini, larutan natrium klorida (zat polutan) disaputkan pada permukaan isolator silicone rubber dengan menggunakan spons dengan lebar lapisan pita konduksi dan lokasi pita konduksi yang telah ditentukan. Dari hasil pengujian, konduktivitas larutan natrium klorida berpengaruh terhadap arus bocor. Pada tegangan uji 20 kV, lokasi ground, lebar lapisan pita konduksi 50 mm, dan nilai konduktivitas larutan NaCl 34,37 mS/cm, nilai arus bocor sebesar 23,58 μA, sedangkan pada nilai konduktivitas larutan NaCl 171,34 mS/cm, nilai arus bocor sebesar 33,23 μA. Semakin besar konduktivitas larutan natrium klorida maka semakin besar pula nilai arus bocor. Selain itu, lokasi pita konduksi berpengaruh terhadap arus bocor. Pada tegangan uji 20 kV, konduktivitas larutan NaCl 171,34 mS/cm, lebar lapisan pita konduksi 50 mm, nilai arus bocor pada lokasi middle sebesar 12 μA. Sedangkan pada lokasi high voltage, nilai arus bocor sebesar 17,37 μA, dan nilai arus bocor pada lokasi ground sebesar 33,23 μA. Dari ketiga lokasi tersebut, nilai arus bocor yang terbesar adalah pada lokasi ground, kemudian high voltage, dan yang paling kecil pada lokasi middle. Lebar lapisan pita konduksi juga berpengaruh terhadap arus bocor yang permukaan isolator silicone rubber. Pada tegangan uji 20 kV, konduktivitas larutan NaCl 171,34 mS/cm, lokasi ground, nilai arus bocor pada lebar lapisan pita konduksi 30 mm adalah 19,19 μA. Sedangkan pada lebar lapisan pita konduksi 40 mm, nilai arus bocor sebesar 19,52 μA, dan nilai arus bocor pada lebar lapisan pita konduksi 50 mm adalah 133,27 μA. Semakin lebar lapisan pita konduksi maka permukaan isolator semakin bersifat konduktif dan arus bocor yang mengalir pada permukaan isolator silicone rubber juga semkain besar.
English Abstract
This study discusses about the testing results from the influence of conduction band location on leakage current flowing on silicone rubber isolator with plate electrode arrangement. To equate the conditions in the field, an impurity is used in the form of liquid sodium chloride to represent the pollutant attached to the silicone rubber insulator. In this study, the liquid sodium chloride (pollutant material) was coated on the surface of the silicone rubber insulator by using a sponge with the specified layer width and location of the conduction band. From the test results, the conductivity of the liquid sodium chloride has an effect on leakage current. At 20 kV test voltage, at the ground location, 50 mm conduction band width, and the conductivity value of liquid NaCl was 34,37 mS / cm, leakage current value equal to 23,58 μA, while at conductivity value of liquid NaCl was 171,34 mS / cm, the leakage current value is 33.23 μA. The greater the conductivity of the liquid sodium chloride, thereby the greater the leakage current value. In addition, the location of the conduction band affects the leakage current. At a test voltage of 20 kV, the conductivity of liquid NaCl was 171,34 mS / cm, the width of the conduction band 50 mm, the leakage current value at the middle location is 12 μA. At high voltage location, the value of leakage current is 17,37 μA, and the leakage current value at ground location is 33,23 μA. From the three locations, the largest value of leakage current is on the ground location, then on the high voltage, and the smallest is on the middle location. The width of the conduction band layer also affects the leakage current of the silicone rubber insulator surface. At 20 kV test voltage, the conductivity of the liquid NaCl was 171.34 mS / cm, at the ground location, the leakage current value at the width of the 30 mm conduction band layer was 19.19 μA. The leakage current value is 19.52 μA in the width of 40 mm conduction band, and the leakage current value at the width of the 50 mm conduction band layer is 133.27 μA. When the width of the conduction band layer, is larger the insulator's surface becomes more conductive and the leakage current flowing on the surface of the silicone rubber insulator is also larger.
