-, Firohman (2019) Analisis Pengaruh Suhu dan Kelembaban terhadap Arus Bocor Isolator Silicone Rubber 20 kV. Sarjana thesis, Universitas Brawijaya.


Salah satu parameter isolator adalah tingkat arus bocor. Ada beberapa macam kondisi lingkungan yang dapat mempengaruhi arus bocor isolator. Didalam penelitian ini dipaparkan tingkat arus bocor pada isolator pos berbahan silicone rubber pada kondisi variasi suhu dan kelembaban. Penelitian ini dilakukan di Laboratorium Tegangan Tinggi Universitas Brawijaya. Untuk kondisi variasi kelembaban digunakan tingkat kelembaban dimulai dari 50% hingga 99% dengan tingkat kenaikan 5%. Untuk kondisi variasi suhu digunakan tingkat suhu dimulai dari 25℃ hingga 70℃ dengan tingkat kenaikan 5℃. Variasi kelembaban dan suhu yang digunakan dimaksudkan untuk mendapatkan nilai arus bocor yang bervariasi sesuai pada kondisi iklim di Indonesia. Tegangan uji yang digunakan adalah tegangan AC berkisar antara 10 kV sampai 30 kV dengan kenaikan tegangan 5 kV.Dari data pengukuran dan analisis didapatkan kesimpulan bahwa arus bocor pada kondisi variasi kelembaban naik secara tidak linier seiring dengan kenaikan tingkat kelembaban dan mengalami kenaikan yang pesat saat nilai kelembaban mendekati maksimum. Sedangkan pada uji variasi suhu, nilai arus bocor naik secara linier, namun dari analisa data menunjukan bahwa pada range suhu 25℃ sampai 70℃ tidak terlalu mempengaruhi nilai arus bocor.

English Abstract

One of parameter that describe insulator is the level of leakage current. There are several reason of environmental conditions that can affect the leakage current level of insulator. In this research, the level of leakage current on postal insulators made from silicone rubber was explained in conditions of variations in temperature and humidity. This research was conducted at High Voltage Laboratory University of Brawijaya. For conditions of variation in humidity, the humidity level starts from 50% to 99% with 5% rate of increase. For conditions of temperature variation, the temperature level starts from 25℃ to 70℃ with 5℃ rate of increase. The variations in humidity and temperature intended to obtain the value of leakage current that vary according to climate conditions in Indonesia. The test voltage used is AC with voltage range starts from 10 kV to 30 kV with 5 kV rate of increase.From the measurement data and analysis, it was concluded that the level of leakage current under humidity variations increased non-linearly along with the increased humidity level and level of leakage current increase rapidly when humidity level approached the maximum level. Whereas in temperature variations, the level of leakage current increase linearly along with the increased temperature level, but from data analysis shows that in the temperature range of 25℃ to 70℃ id does not significantly affect the value of the leakage current.
