Abstract

This study aims to analyze the impact of radiator leakage in the main transformer on the power generation performance at the Ampelgading Hydroelectric Power Plant, Malang. Radiator leakage reduces the volume of insulating oil, leading to increased operating temperatures and degradation of insulation quality. A quantitative descriptive method with a case study approach was employed by analyzing temperature data, Breakdown Voltage (BDV), Dissolved Gas Analysis (DGA), and energy production data before and after the disturbance. The results indicate that radiator leakage caused a significant increase in winding and oil temperatures, along with a decline in insulation oil quality marked by elevated dissolved gas levels. Operationally, the disturbance resulted in a power output reduction of 18.27%. Corrective actions, including cold welding, load reduction, and oil purification, were effective in restoring transformer performance, as evidenced by an average BDV value of 68.1 kV categorized as very good, and improved energy production after maintenance. This study concludes that the reliability of the transformer cooling system, particularly the radiator, plays a crucial role in maintaining operational stability and efficiency in hydroelectric power generation.

Abstract

Abstrak—Peredaran c-bank atau kompensator atau kapasitor bank, banyak dijual dipasaran dan ditawarkan kepada konsumen listrik rumah tangga dengan informasi dapat menurunkan biaya pembayaran listrik. Masyarakat pengguna listrik masih belum mendapatkan informasi yang jelas, apakah c-bank ini dapat menurunkan konsumsi pemakaian energi listrik, yang juga berdampak kepada pembayaran listrik. Penelitian ini bertujuan untuk mengevaluasi efektivitas kompensator 1 fasa dalam mengurangi konsumsi daya dan energi listrik. 5 buah kompensator tunggal masing-masing dipasangkan pada 6 beban listrik tunggal dan 7 buah kompensator sentral dihubungkan pada 10 beban rumah tangga. Berdasarkan hasil penelitian bahwa kompensator hanya berpengaruh terhadap perubahan daya semu dan daya reaktif sedangkan daya nyata tidak berubah secara signifikan. Perbaikan faktor daya berpengaruh kepada penambahan daya semu namun tidak berpengaruh kepada biaya pemakaian energi listrik. Pemasangan kompensator yang tidak sesuai dengan kebutuhan beban dapat menurunkan nilai faktor daya beban dari sebelumnya.
