“…Pengukuran arus bocor dengan penuaan dipercepat di lab menggunakan sinar ultraviolet pada isolator resin epoksi dengan abu sekam padi menunjukkan semakin lama penyinaran maka nilai arus bocor rata-rata akan semakin meningkat dimana kerusakan permukaan isolator terjadi akibat penyinaran ultraviolet secara terus menerus [5] Penggunaan silicone rubber (SiR) memiliki kemampuan untuk memperbaiki kualitas permukaan isolator agar bersifat menolak air. Sehingga digunakan silicone rubber dicampur dengan resin epoksi untuk mengurangi penggunaan resin epoksi.…”

“…Gambar 16. Grafik rata-rata arus bocor terhadap lama penyinaran ultraviolet [12] Kenaikan rata-rata arus bocor lucutan awal dan arus puncak disebabkan karena saat isolator terkena sinar ultraviolet maka akan terjadi proses penyerapan radiasi yang dapat menyebabkan pemutusan ikatan kovalen pada permukaan isolator sehingga dapat terjadi oksidasi yang menyebabkan terjadinya reaksi kimia pada isolator sehingga mempengaruhi karakteristik isolator.…”

AbstrakRiset terhadap bahan isolator polimer yang lebih ringan dan dapat ditambahkan pengisi untuk memperbaiki kekuatan isolator masih menjadi sebuah riset, namun kondisi lingkungan akan mempengaruhi kinerja pada isolator polimer di luar ruangan. Pada penelitian ini dilakukan pengukuran arus bocor kondisi basah terhadap permukaan bahan isolator dengan metode pengukuran Inclaned-Planed Tracking (IEC 587:1984) dengan kontaminan NH 4 Cl dan air hujan. Sampel pengukuran menggunakan bahan isolasi resin epoksi yang terbuat dari campuran DGEBA dan MPDA dengan campuran bahan pengisi silicone rubber dan fly ash. Penuaan dipercepat dilakukan dalam kotak pengukuran yang terdapat paparan radiasi ultraviolet. Parameter yang dianalisa adalah sudut kontak, arus bocor lucutan pertama dan arus puncak. Hasil pengukuran menunjukkan semakin lama radiasi ultraviolet menyebabkan penurunan hidrofobik permukaan dan meningkatnya nilai arus bocor. Penggunaan polutan dengan nilai konduktivitas tinggi menyebabkan semakin tingginya arus bocor lucutan pertama dan arus puncak pada permukaan isolator. Didapatkan penggunaan komposisi pengisi terbaik terdapat pada sampel uji RTV23 dibandingkan RTV22 dan RTV24 dengan daya tahan sudut hidrofobik paling stabil sebesar 48.56% dan rata-rata kenaikan nilai arus bocor lucutan awal sebesar 31.16% dan arus puncak 10.76% terhadap penuaan radiasi ultraviolet.Kata kunci : resin epoksi, fly ash, variasi kontaminan, penuaan dipercepat, sudut kontak, arus bocor. AbstractResearch on polymer insulator material that is lighter and can be added filler to improve the strength of the insulator is still a research, but environmental conditions will affect the performance of outdoor polymer insulators. In this research, we measured leakage current in wet condition on surface of insulating material with Inclaned-Planed Tracking measurement method (IEC 587:1984) with contaminant of NH4Cl and rainwater. The measurement sample used an epoxy resin insulation material made from a mixture of DGEBA and MPDA with a mixture of silicone rubber and fly ash. Accelerated aging is done in a measurement box with exposure of ultraviolet radiation. Parameters analyzed were contact angle, first leakage current and peak current. The measurements show longer ultraviolet radiation causes decrease in surface hydrophobicity and increased value of leakage current. The use of pollutants with high conductivity values leads to higher leakage current first and peak current on the surface of the insulator. The best use of filler composition was found in RTV23 test sample compared to RTV22 and RTV24 with the most stable hydrophobic of 48.56% and an average rise in initial discharge leakage value of 31.16% and a peak current of 10.76% against aging of ultraviolet radiation.

“…The addition of silicon rubber and silica in epoxy resin material causes the surface became rougher because of the quantity of silica sand are increasing, as well as increasing silicon rubber, causing methyl element content at the surface increases. When the low molecular weight silicon rubber containing methyl groups increasingly lead to more rough surface, such as the SEM images that have been done [1] on the polymer insulation materials EP-RHA for the RHA + polysiloxane composition of 30% and 50%.…”

Currently, epoxy resin has been developing as outdoor insulator replace ceramic and glass insulator, because epoxy resin has some dielectric properties better than the ceramic, glass and porcelain material. When epoxy resin was used as outdoor insulator, some factors affecting performance of epoxy resin insulators are like rain, humidity, ultraviolet rays, condensation and contaminant. To improve the surface properties of epoxy resin, then silicon rubber material that has the ability to repel water were added and silica sand was mixed with silicone rubber to improve the mechanical properties. When contaminant flows at the insulator surface, they can cause damage to the surface of the insulator and it was formed tracking on insulator surface and finally cause flashover. This paper presents the morphological studies of epoxy resin sample test after electrical tracking. The tests were conducted at high voltage laboratory with 3.5 kV AC high voltage and 50 Hz. NH4C1 contaminant was flowed on test sample surface during 6minutes. After electrical aging was done then samples were taken using SEM devices to be analyzed of morphological condition.The research results showed that epoxy resin material with filled mixtures of silicon rubber and silica 30% (RTV23) did not experience significant damage after electrical tracking by the Inclined Plane Tracking test method.
