Abstract

In electronic equipment such as computers, printers, UPS, scanners, inverters, converters, etc. are non-linear loads. Non-linear loads are loads where the relationship between current and voltage is not linear. The existence of non-linear loads in the electric power system will cause harmonic disturbances. Total Harmonic Distortion (THD) of voltages and currents that do not meet IEEE 519 standards can result in losses in the distribution transformer, which will cause disturbances in the electric power system. Harmonic levels that exceed these standards can cause an increase in heat to the equipment. Even in the worst conditions there can be interference (hanging up) and even permanent damage to some sensitive electronic equipment including computers (Personal Computers) and besides that it can also cause a decrease in the life of the equipment. The methods used in this research are literature studies, field studies and data analysis methods. Literature study is looking for relevant references and theories. Field studies by collecting data in the field. Furthermore, data analysis was carried out by measuring the harmonic content of voltage and electric current in the District 8 Building, especially the Treasury Tower Building on the Low Main Panel (PUTR). Measurements were made using the Circutor e-BOX 1500 measuring instrument for 7 x 24 consecutive working hours (non-stop) in accordance with the provisions of SPLN D5.004-1,2012. The measurement results will then be compared with the IEEE 519-2014 standard, as an evaluation of the quality of electrical power in the Treasury District 8 Building. The conclusion of the analysis shows that the current harmonic content (%THDI) in the Treasury District 8 Building is 10% to 40% above the standard limit of 8% from IEEE-519-2014. However, for Total Harmonic Distortion Voltage (THDv), 1-3% is still below 5% of the IEEE-519-2014 standard limit, so it can be recommended to install an Active Harmonic Filter (AHF) to reduce the THDI and THDV values according to the IEEE-519-2014 standard. Keywords : nonlinear load, filter active harmonics, harmonics. Pada peralatan elektronik seperti komputer, printer, UPS, scanner, inverter, konverter, dan lain-lain merupakan beban-beban non-linier. Beban non-linier adalah beban dimana hubungan antara arus dan tegangannya tidak linier. Keberadaan beban non-linier pada sistem tenaga listrik akan menimbulkan gangguan harmonisa. Total Harmonic Distortion (THD) tegangan dan arus yang tidak memenuhi standar IEEE 519-2014 dapat mengakibatkan terjadinya losses pada trafo distribusi, sehingga akan menyebabkan gangguan pada sistem tenaga listrik. Tingkat harmonisa yang melewati standar tersebut dapat menyebabkan terjadinya peningkatan panas pada peralatan. Bahkan pada kondisi terburuk dapat terjadi gangguan (hanging up) bahkan kerusakan permanen pada beberapa peralatan elektronik yang sensitive termasuk komputer (Personal Computer) dan selain itu juga dapat menyebabkan berkurangnya umur peralatan. Metode yang digunakan dalam penelitian tugas akhir ini yaitu studi literatur, studi lapangan dan metode analisis data. Studi literatur yaitu mencari referensi dan teori yang relefan. Studi lapangan dengan melakukan pengumpulan data yang ada di lapangan. Selanjutnya dilakukan analisa data dengan melakukan pengukuran kandungan harmonisa tegangan dan arus listrik di Gedung District 8 khususnya Gedung Tower Tresury pada Panel Utama Tegangan Rendah (PUTR). Pengukuran dilakukan dengan menggunakan alat ukur Circutor e-BOX 1500 selama 7 x 24 jam kerja berturut-turut (non stop) sesuai dengan ketentuan SPLN D5.004-1,2012. Hasil pengukuran selanjutnya akan dibandingkan dengan standar IEEE 519-2014, sebagai evaluasi terhadap kualitas daya listrik di Gedung Treasury District 8. Kesimpulan dari hasil analisis menunjukkan bahwa kandungan harmonisa arus (%THDI) di Gedung Treasury District 8 yaitu 10% hingga 40% diatas batasan standard 8% dari IEEE-519-2014. Namun untuk Total Harmonic Distortion Voltage (THDv) diperoleh 1-3% masih dibawah 5% dari batasan standard IEEE-519-2014 sehingga dapat direkomendasikan pemasangan Active Harmonic Filter (AHF) guna menurunkan nilai THDI dan THDV sesuai standard IEEE-519-2014.. Kata kunci : beban nonlinier, filte harmonisa aktif, harmonisa.
