ARUS BOCOR PADA SILICONE RUBBER YANG DIBERI POLUTAN KALSIUM SULFAT

---

Penelitian ini membahas mengenai terjadinya arus bocor pada material isolasi silicone rubber yang terkontaminasi kalsium sulfat dengan variasi waktu pengkondisian 1,3, dan 5 hari, serta tanpa pengkondisian sebagai pembanding. Sampel uji berupa silicone rubber RTV 497 yang dibentuk leaf-like sample berdimensi 50 x 25 x 1 mm yang dihubungkan dengan aluminium tape pada kedua sisi sampel dengan jarak sela 5 mm. Sampel uji diberikan perlakuan kontaminasi menggunakan larutan kalsium sulfat di dalam chamber pengkondisian. Tegangan yang diaplikasikan sebesar 220 V, 500 V, dan 1000 V untuk mengetahui besar nilai arus bocor yang melewati permukaan sampel uji. Hasil pengujian didapatkan nilai arus bocor rata-rata pada variasi tanpa pengkondisian; 1 ;3; dan 5 hari pengkondisian pada aplikasi tegangan 220V berturut-turut sebesar 0,02474; 0,02738;0,02870; dan 0,02880 mA. Pada aplikasi tegangan 500V sebesar 0,02488; 0,02754; 0,02886; dan 0,02901 mA. Pada aplikasi tegangan 1000V sebesar 0,02500; 0,02755; 0,02898; dan 0,02915 mA. Hasil pengukuran menunjukkan bahwa nilai arus bocor meningkat seiring dengan bertambahnya waktu pengkondisian kalsium sulfat dan besarnya tegangan yang diaplikasikan. Lama pengkondisian isolasi silicone rubber terpapar kalsium sulfat akan menyebabkan akumulasi kontaminan pada permukaan isolasi, sehingga secara signifikan meningkatkan nilai arus bocor. This study discusses the occurrence of leakage current on silicone rubber insulation material contaminated with calcium sulfate, with conditioning times of 1, 3, and 5 days, as well as an unconditioned sample for comparison. The test samples consist of RTV 497 silicone rubber, molded into a leaf-like shape with dimensions of 50 x 25 x 1 mm, and connected with aluminum tape on both sides with a 5 mm gap. The test samples were treated with calcium sulfate solution contamination in a conditioning chamber. Voltages of 220 V, 500 V, and 1000 V were applied to measure the leakage current passing through the sample surface. The test results showed that the average leakage current values at 220 V for unconditioned, 1-day, 3-day, and 5-day conditioned samples were 0.02474, 0.02738, 0.02870, and 0.02880 mA, respectively. At 500 V, the values were 0.02488, 0.02754, 0.02886, and 0.02901 mA, and at 1000 V, they were 0.02500, 0.02755, 0.02898, and 0.02915 mA, respectively. The results indicate that leakage current values increase with longer calcium sulfate conditioning times and higher applied voltages. The prolonged conditioning of silicone rubber insulation exposed to calcium sulfate results in the accumulation of contaminants on the insulation surface, significantly increasing leakage current values.
