Abstract

Skripsi ini membahas identifikasi pola Partial Discharge (PD Pattern) pada switch Larken EB-21 dengan variasi penurunan tekanan udara Proses pengukuran dilakukan dengan sistem elektroda switch yang ditempatkan di dalam gas test chamber. Selanjutnya dilakukan proses vacuum untuk mengurangi tekanan udara yang terdapat di dalam gas test chamber dengan nilai tekanan tekanan udara dari 766,5 mmHg, lalu divakumkan dengan nilai penurunan tekanan udara sebesar -50; -100; -150; -200; dan -250 mmHg. Perekaman data dilakukan selama 50 detik pada kenaikkan tegangan 1.1; 1.2; dan 1.3 dari nilai PDIV yang didapatkan. Hasil pengukuran pola PD menunjukkan bahwa pada variabel kontrol, didapatkan persentase kemungkinan terjadinya PD pada kenaikkan tegangan 1.1; 1,2; dan 1.3 dari nilai PDIV sebesar 17,04; 21; dan 21,6 % . Time lag akan semakin lama seiring turunnya tekanan udara. Pada saat penurunan tekanan udara hingga -250 mmHg, persentase kemungkinan terjadinya PD menjadi 5,77% dan Time lag menjadi 12.165 ms. Dari hasil tersebut menunjukkan bahwa kemungkinan terjadinya PD akan semakin kecil dan time lag yang terjadi akan semakin panjang seiring berkurangnya tekanan udara. This research reports the results of identifying the Partial Discharge pattern (PD Pattern) on the Larken EB-21 switch with variations in air pressure reduction. The measurement process was carried out with a switch electrode system placed in the gas test chamber. Next, a vacuum process is carried out to reduce the air pressure in the gas test chamber with an air pressure value of 766.5 mmHg, then vacuum with an air pressure reduction value of -50; -100; -150; -200; and -250 mmHg. Data recording was carried out for 50 seconds at a voltage increase of 1.1; 1.2; and 1.3 of the PDIV value obtained. The PD pattern measurement results show that for the control variable, the percentage probability of PD occurring with an increase in voltage is 1.1; 1.2; and 1.3 from the PDIV value of 17.04; 21; and 21.6%. The time lag will get longer as the air pressure drops. When the air pressure decreases to -250 mmHg, the percentage of probability of PD occurring becomes 5.77% and the time lag becomes 12,165 ms. These results show that the possibility of PD will be smaller and the time lag that occurs will be longer as the air pressure decreases.
