Abstract

Insulating oil is a type of insulator that is widely used as insulation in electrical equipment such as transformers. The insulating oil in the transformer functions as insulation in the transformer windings so that flashover does not occur and causes voltage leaks to the outside of the transformer, then the insulating oil also functions as a transformer coolant. Generally, the insulating oil used today is made from mineral oil which cannot be renewed so its availability is limited and may run out in the future. In an effort to reduce the use of mineral oil as a basic ingredient for insulating oil, it is necessary to develop a basic ingredient for making insulating oil, which can use vegetable oils such as crude palm oil (CPO) with the additive butylated hydroxytoulene added. In testing the suitability of crude palm oil with the addition of butylated hydroxytoulene additive as insulating oil, breakdown voltage testing was carried out using Megger OTS80Af and viscosity. Based on the test results, the highest breakdown voltage value was obtained for crude palm oil with the addition of butylated hydroxytoulene of 11.13 kV and a viscosity of 27.12 cSt. From the test results, it can be concluded that crude palm oil with the addition of butylated hydroxytoulene is not suitable for use as transformer insulating oil because it cannot meet the standard SPLN 49-91: 1982, the breakdown voltage of transformer insulating oil is 30 kV/2.5 mm.

Abstract

Penggunaan energi listrik tenaga surya merupakan salah satu bentuk upaya konservasi peggunaan energi. Karena energi surya merupakan salah satu bentuk energi terbarukan yang tersedia sepanjang tahun secara gratis. Selain merupakan energi terbarukan, energi surya juga relative ramah lingkungan karena dalam memproduksi energi nya tidak menghasilkan limbah ikutan. Pada sistem tenaga listrik tenaga surya, energi matahari dikonversikan menjadi energi listrik melalui konversi langsung sel-surya. Kegiatan pengabdian pada masyarakat ini dilaksanakan di RT 15 LK 2 kelurahan Rajabasa Nunyai, kecamatan Rajabasa, Bandar Lampung. Dengan metode pelaksanaan kegiatan pengabdian dilaksankan dengan pelatihan pengetahuan dasar kelistrikan untuk dapat mengetahui dan merakit sistem pembangkit tenaga surya bagi masyarakat. Tujuan lain kegiatan pengabdian ini adalah sebagai sarana untuk mengedukasi masyarakat tentang kemungkinan penggunaan sumber energi listrik alternatif yang dapat dimanfaatkan untuk kehidupan sehar-hari. Setelah kegiatan pengenalan dilaksanakan, kegiatan dilanjutkan dengan kegiatan pemasangan panel lampu jalan pada 5 titik yang telah disepakati para anggota kegiatan dan masyarakat. Lampu penerangan yang diperguanakan merupakan lampu LED berdaya 90 watt. Dari hasil pemasangan lampu jalan umum didapat bahwa lampu jalan dapat bekerja dengan baik dan menerangi jalan di sekitar pemukiman penduduk.
