P Penggunaan peralatan listrik berbeban non-linear di Gedung Elektro Universitas Trisakti meningkatkan permasalahan kualitas daya, terutama akibat gangguan harmonisa yang menyebabkan distorsi arus dengan kandungan Total Harmonic Distortion (THD) yang tinggi. Kondisi ini dapat menyebabkan berbagai masalah, seperti pemanasan konduktor, overheating pada transformator, peningkatan beban chiller, dan naiknya arus netral. Penelitian ini bertujuan untuk menganalisis kualitas daya harmonisa serta dampaknya terhadap umur pakai transformator menggunakan metode kuantitatif. Data diambil melalui pengukuran lapangan dan dianalisis berdasarkan standar SPLN 17:1979, IEEE 519-2014, IEEE 446-1995, dan IEC 61000-4-30. Hasil menunjukkan bahwa persentase pembebanan transformator 630 kVA tertinggi sebesar 26,03% masih berada dalam batas aman. THD arus dan tegangan juga memenuhi standar yang ditetapkan. Pengaruh harmonisa terhadap umur transformator relatif kecil, dengan laju penuaan sebesar 0,0811 pu/bulan. Berdasarkan hasil tersebut, transformator diperkirakan masih dapat beroperasi selama 15 tahun ke depan. Penting dilakukan inspeksi rutin terhadap kualitas daya harmonisa untuk deteksi dini masalah, pengoperasian transformator sesuai kapasitas, dan perencanaan umur pakai transformator secara optimal.
T The use of non-linear load electrical equipment in the Electrical Engineering Building of Trisakti University has increased power quality issues, particularly due to harmonics disturbances that cause current distortion with high Total Harmonic Distortion (THD). This condition can lead to various problems such as conductor overheating, transformer overheating, increased chiller load, and rising neutral current. This study aims to analyze harmonic power quality and its impact on transformer lifespan using a quantitative method. Data were collected through field measurements and analyzed based on SPLN 17:1979, IEEE 519-2014, IEEE 446-1995, and IEC 61000-4-30 standards. The results showed that the highest transformer load percentage of 630 kVA, at 26.03%, remains within safe limits. Current and voltage THD also comply with the established standards. The impact of harmonics on transformer lifespan is relatively small, with an aging rate of 0.0811 pu/month. Based on these findings, the transformer is estimated to continue operating for the next 15 years. Routine inspections of harmonic power quality are essential for early detection of issues, operating transformers within capacity, and optimizing transformer lifespan planning.
