Abstract

The performances of outdoor polymeric insulators are influenced by environmental conditions. This paper presents the effect of artificial tropical climate on the hydrophobicity, equivalent salt deposit density (ESDD), surface leakage current, flashover voltage, and surface degradation on epoxy-polysiloxane polymeric insulator materials with rice husk ash (RHA). Test samples are made at room temperature vulcanized (RTV) of various composition of epoxy-polysiloxane with rice husk ash as filler. The aging was carried out in test chamber at temperature from 50oC to 62oC, relative humidity of 60% to 80%, and ultraviolet (UV)  radiation 21.28 w/cm2 in daylight conditions for 96 hours. The experiment results showed that the flashover voltage fluctuates from 34.13 kV up to 40.92 kV and tends to decrease on each variation of material composition. The surface leakage current fluctuates and tends to increase. Test samples with higher filler content result greater hydrophobicity, smaller equivalent salt deposit density, and smaller critical leakage current, which caused the increase of the flashover voltage. Insulator material (RTVEP3)showed the best performance in tropical climate environment. Artificial tropical aging for short duration gives less effect to the surface degradation of epoxy-polysiloxane insulator material. DOI: http://dx.doi.org/10.11591/telkomnika.v10i4.846

Abstract

Dalam penelitian ini, sistim yang dikembangkan berbasis Teknologi Internet of Things (IoT) yang dibangun terdiri atas: perangkat embedded system yang berfungsi untuk melakukan pengukuran dan pengiriman data, perangkat lunak Web Service yang berfungsi untuk menerima data dari sensor system dan perangkat lunak berbasis Arduino menggunakan flatform aplikasi Blynk Cloud dalam penyajian data dan pengelolaan data untuk melalui perangkat display perangkat android. Sistim ini dibangun untuk memberikan fungsi peringatan dini terhadap anomali parameter trafo seperti overload, overvoltage dan unbalance load. Berdasarkan pengujian, waktu yang di butuhkan untuk mengirim dan menerima notifikasi di smartphone user melalui aplikasi blynk berkisar pada 3-4 detik. Dengan menetapkan batas tolerasi tertentu sebagai batas ambang ketidakseimbangan, maka pada saat beban sangat tidak seimbang dimana arus netral hampr sama atau lebih besar dari arus phasa maka pada lampu indiator lokal akan menyala dan pada sistim android akan memberikan indikator unbalance load.
