Abstract

Perkembangan teknologi telekomunikasi saat ini, telah mencapai teknologi 4G LTE, bahkan sudah ada yang menerapkan teknologi 5G. Salah satu infrastruktur yang menunjang kemajuan teknologi telekomunikasi tersebut adalah BTS. Komponen pada BTS antara lain, rectifier, microwave link, perangkat radio BTS, air conditioner (AC). Komponen ini termasuk kategori beban listrik nonlinier yang menimbulkan masalah harmonisa pada BTS. Oleh karena itu, perlu dilakukan pengukuran tingkat harmonisa pada setiap BTS untuk dilakukan kajian yang mencakup tingkat distorsi harmonisa tegangan dan arus akibat komponen nonlinier pada BTS termasuk BTS di Gedung Laboratorium Program Studi Teknik Mesin, Fakultas Teknik, UKI Jakarta. Berdasarkan pengukuran harmonisa yang dilakukan pada BTS ini, diperoleh hasil yaitu: BTS memiliki nilai total distorsi arus, THDi sebesar 10,16% yang melebihi standar IEEE 519-2014. Nilai total distorsi tegangan, THDv sebesar 1,11%, telah memenuhi standar IEEE 519-2014. Nilai THDi dominan pada BTS terjadi pada orde ke-3 dengan THDi sebesar 8,7% dan orde ke-5 dengan THDi sebesar 4,2% melebihi batas 4% dari standar IEEE 519-2014. Tingkat faktor daya listrik pada BTS rendah sebesar 0,423 tidak memenuhi syarat faktor daya ≥ 0.85 dari standar PLN. Kata Kunci: BTS, distorsi gelombang, harmonisa, THD. / The current development of telecommunications technology has reached 4G LTE technology, and some have even implemented 5G technology. One of the infrastructures that supports the advancement of telecommunication technology is the BTS. Components in BTS include, rectifier, microwave link, BTS radio equipment, air conditioner (AC). This component belongs to the category of nonlinear electrical loads which cause harmonic problems in BTS. Therefore, it is necessary to measure the harmonic level at each BTS for a study that includes the level of voltage and current harmonic distortion due to nonlinear components in BTS including BTS in the Mechanical Engineering Study Program Laboratory Building, Faculty of Engineering, UKI Jakarta. Based on the harmonic measurements carried out on this BTS, the results obtained are: BTS has a total current distortion value, THDi of 10.16% which exceeds the IEEE 519-2014 standard. The total value of voltage distortion, THDv is 1.11%, which still meets the IEEE 519-2014 standard. The dominant THDi value in BTS occurs in the 3rd order with a THDi of 8.7% and the 5th order with a THDi of 4.2% exceeding the 4% limit of the IEEE 519-2014 standard. The power factor level for low BTS is 0.423, which does not meet the power factor requirement of ≥ 0.85 from the PLN standard. Keywords: BTS, harmonics, THD, wave distortion
