Abstract

Fenomena pre-breakdown voltage adalah suatu fenomena kegagalan dielektrik pada media isolasi cair. Fenomena tersebut dapat mempengaruhi kinerja suatu media isolasi cair. Semakin cepat suatu bahan isolasi cair mengalami fenomena pre-breakdown voltage, sehingga kekuatan dielektrik bahan isolasi tersebut mengalami penurunan. Dalam pengujian ini akan dilakukan pengamatan fenomena pre-breakdown voltage pada bahan isolasi cair dengan menggunakan pembangkitan tegangan tinggi DC skala laboratorium. Pada proses pengujian, yang dilakukan pengukuran arus menggunakan NI 9246 yang disambungkan dengan computer yang terdapat perangkat lunak LabVIEW dan diolah menggunakan perangkat lunak DIAdem. Dalam waktu yang bersamaan, fenomena pre-breakdown voltage akan direkam menggunakan kamera beresolusi tinggi agar mendapatkan gambar yang baik. Data arus yang direkam oleh akuisisi data disinkronkan dengan gambar yang terambil oleh kamera pada isolasi minyak selama pengujian. Dari eksperimen tersebut dapat diketahui karakteristik arus pada saat fenomena pre-breakdown voltage pada isolasi minyak jagung. Hasil pengujian menunjukkan bahwa fenomena pre-breakdown voltage terjadi pada isolasi minyak Jagung dengan tegangan pembangkitan antara 38 kV hingga 40 kV dan nilai arus yang terukur pada akuisisi data ketika terjadi fenomena tersebut adalah 130 mA - 280 mA. Kata Kunci: Isolasi Cair Minyak Jagung, Karakteristik Fenomena pre-breakdwon voltage. ============== Phenomenon pre-breakdown voltage is a phenomenon of failures dielectrics to the media isolation. The phenomenon can update a performance of a work of the media isolation of liquidity. The faster of the materials isolation liquidity sustain of phenomenon pre-breakdown voltage, with the result that the power of liquidity sustaining decreased. In this experimentation will do an observation of phenomenon pre-breakdown voltage at isolation of liquidity using the DC high voltage generation in the scales of the laboratory. On prosses of the experiment, will perform of measuring by using NI9246 to link with the computer has LabVIEW accessed and the process uses a Diadem software. In the same time, phenomenon pre-breakdown voltage will record with the high-resolution camera for good quality of the pictures. The data must record with an acquisition data synced with images that already taken during the experiment isolation of oils. From the experiment can be known the characteristic of the phenomenon pre-breakdown voltage at the isolation of corn’s oils.The result of experimentation showing the phenomenon of pre-breakdown voltage happens at the isolation of corn’s oils with generator voltage about 38kv to 40 the number measured at an acquisition data happen while the phenomenon is about 130 mA -280mA Keywords: isolation liquidity of corn’s oils, characteristic Pre-Breakdown Voltage of the phenomenon
