Abstract

Listrik merupakan kebutuhan penting dalam kehidupan modern sehingga ketersediaan listrik yang stabil menjadi kunci dalam mencapai keseimbangan lingkungan dan mendukung kemajuan masyarakat. Saluran transmisi listrik terdiri dari tower transmisi yang menyalurkan energi dari pembangkit listrik ke konsumen. Namun, tower transmisi rentan terhadap gangguan eksternal terutama sambaran petir yang dapat menyebabkan lonjakan tegangan dan mengganggu sistem kelistrikan. Perlindungan sistem transmisi dari dampak tersebut memerlukan penggunaan transmission line surge arrester (TLA). Penelitian ini bertujuan untuk menganalisis dampak sambaran petir terhadap kawat fasa serta mengevaluasi efektivitas pemasangan TLA pada tower transmisi di wilayah kerja Gardu Induk Solok. Simulasi dilakukan menggunakan software alternative transient program (ATP), dengan parameter tower transmisi yang disesuaikan dengan standar kelistrikan di Indonesia. Variasi arus sambaran petir sebesar 30, 40, dan 50 kA serta waktu muka dan ekor 1,2/50 μs digunakan dalam simulasi untuk mengkaji kenaikan tegangan induksi pada setiap fasa. Hasil simulasi menunjukkan bahwa semakin besar arus petir, semakin tinggi tegangan lebih yang terjadi pada saluran transmisi. Setelah pemasangan TLA, hasil simulasi menunjukkan bahwa alat tersebut mampu mereduksi tegangan lebih akibat petir dengan efektivitas antara 73% hingga 87%. Dengan demikian, penelitian ini membuktikan bahwa TLA sangat efektif dalam mengurangi lonjakan tegangan akibat sambaran petir, sehingga meningkatkan keandalan sistem transmisi listrik.

Abstract

This study details the design and experimental evaluation of an off-grid photovoltaic (PV) system equipped with an automatic solar panel cleaning mechanism to address performance degradation due to dust accumulation. The system integrates a mechanical wiper-based cleaning unit, solar charge controller (SCC), inverter, and low-voltage disconnect (LVD) to maintain reliable and stable operation in stand-alone settings. Experimental tests were performed on a 50 Wp PV module under actual outdoor conditions in Padang, Indonesia. System performance was assessed before and after panel cleaning using key electrical parameters, such as output voltage, current, output power, and relative efficiency improvement. Results show that the automatic cleaning mechanism increased the average PV output power from 0.88 W to 1.71 W, representing an efficiency improvement of approximately 11.89% compared to the uncleaned state. In contrast to previous studies that focus on grid-connected systems or manual cleaning methods, this research introduces a low-cost, self-operating cleaning solution tailored for small-scale off-grid PV applications in tropical environments. The proposed system offers practical benefits for enhancing energy yield, system reliability, and maintenance efficiency in remote solar installations.
