Abstract
Penelitian ini membahas tentang bagaimana pengaruh dari perubahan nilai konduktivitas, perubahan letak objek uji serta perubahan nilai tegangan uji terhadap perubahan nilai arus bocor pengukuran pada permukaan isolator kaca. Perubahan nilai konduktivitas mempengaruhi perubahan nilai arus bocor pengukuran pada permukaan isolator kaca, perubahan nilai konduktivitas berbanding lurus terhadap perubahan nilai arus bocor. Semakin luas permukaan objek uji berbanding lurus terhadap kenaikan nilai arus bocor pengukuran pada permukaan isolator kaca dengan perubahan tegangan uji. Berdasarkan pengujian pengaruh dari perubahan masa garam (gr) yang mempenggaruhi nilai moll larutan NaCl (moll), konsentrasi larutan NaCl (molar) dan nilai konduktivitas larutan NaCl (mS/cm) terhadap perubahan nilai arus bocor pengukuran pada permukaan isolator kaca. Semakin meningkat massa (gr) NaCl, moll larutan NaCl meningkat maka, meningkat juga nilai konduktivitas (mS/cm). Variasi luas objek uji yang terkontaminasi mempengaruhi nilai arus bocor pengukuran pada permukaan isolator kaca dengan perubahan nilai tegangan uji. Hasil penelitian nilai konduktivitas terkecil yakni dengan 250 ml air mineral, 3 gr NaCl, yakni sebesar 20,68 mS/cm. Nilai konduktivitas dengan nilai terbesar yakni dengan 250 ml air mineral, 30 gr NaCl, yakni sebesar 205,58 mS/cm.untuk nilai dari pengaruh konduktivitas terendah larutan NaCl terhadap arus bocor dengan tegangan uji 25 kV pada variasi OBA-4 = 45,25 μA, pada variasi OBB-4 = 39,30 μA. Untuk pengaruh nilai konduktivitas terbesar terhadap arus bocor pada 25 kV pada variasi OBA-4 = 69,06 μA, pada variasi OBB-4 = 51,41 μA. Luas permukaan objek uji yang terkontaminas berbanding lurus terhadap perubahan nilai arus bocor permukaan dengan variasi kondutivitas dan perubahan tegangan uji. Semakin tinggi nilai konduktivitas dan semakin luas permukaan objek uji yang terkontaminasi terhadap perubahan tegangan uji, maka akan semakin tinggi nilai arus bocor pengukuran pada permukaan isolator kaca. Perubahan nilai arus bocor berbanding terbalik terhadap nilai tahanan permukaan (MΩ), berbanding lurus terhadap nilai rugi daya (Watt) dan nilai rugi energi dalam satu tahun (kWh).
English Abstract
This result discusses how the effect of changes in conductivity values, changes in the location of the test object and changes in the value of the test voltage to changes in the value of leakage current measurements on the surface of the glass insulator. The change of conductivity value influences the change of leakage current value of measurement on the surface of glass insulator, the change of conductivity value is directly proportional to the change of leakage current value. The more surface area of the test object is directly proportional to the increase of the measured leakage current’s value on the surface of the glass insulator with the change of test voltage. From this results of research the effect about the change of salt's mass value (gr) which is affecting of the moll's value of NaCl (moll) and the concentration of NaCl's solution (molar) and the conductivity value of NaCl (mS / cm) to the change of leakage current,s value on the surface of glass insulator.when the mass of NaCl (gr) more increasing, moll will increas (moll) and the conductivity more increasing (mS/cm). The variety of the object which is that contaminated by the polutions will changes the value of leakage current’s value with the changes of the voltage’s value. The conductivity value with the largest value with 250 ml of mineral water, 30 g NaCl, ie 205.58 mS / cm.for the value of the lowest conductivity effect of NaCl solution to leakage current with 25 kV test voltage on OBA-4 = 45,25 μA, on the variation of OBB-4 = 39.30 μA. For the effect of the greatest conductivity value on leakage current at 25 kV on OBA-4 variation = 69,06 μA, on variation OBB-4 = 51,41 μA.the surface area of the object which is contaminated by polution, the value will directly proportional of leakage current’s value with the variasion of conductivity and the voltage’s value. If the value of conductivity increased, and more large the area of condutivity the value of leakage current more ncreases. The change of the leakage current’s value is inversely proportional to the value of surface resistance (MΩ), proportional to the value of power loss (Watt) and the energy loss value in one year (kWh).
