“…For typical CFLs tested in [36], the THD in the input current is as high as 75%, while the CFL examined in [37] has a total harmonic current distortion factor ( THD i ) equal to 67.7%. Such harmonic pollution is high and may degrade power quality noticeably.…”

In normal operating conditions, the mains voltage level provided by low-voltage distribution networks follows time-varying patterns within permissible limits. The statistical characterisation of disturbances inserted into the power grid by nonlinear electrical devices is useful since operators are able to establish power quality limits and assess the residual capacity of networks for new smart installations, which may include a multitude of power electronic devices. Existing standards related to emission tests recommend using a power supply source in the measurement circuit with a nominal voltage parameter. However, the range of permissible variations of relevant supply voltage parameters may have an impact on conducted emissions. It can also be considered that the symptoms of supply voltage variations may manifest themselves differently depending on the equipment’s architecture and also the range of frequency observation with reference to harmonics and supraharmonics. The purpose of this study is to measure and analyze non-intentional conducted emissions injected into the power grid by lighting devices, methodically, by numbers of studies under different supply voltage conditions within two frequency bands. The emission is evaluated separately in two ranges: up to 2 kHz and 9-150 kHz. Obtained results show that the level of conducted emission introduced into the low voltage network by modern lighting sources like fluorescent and LED lamps varies with the supply voltage level compared to the emission generated in the nominal voltage level condition. Additionally, in the case of a spectrum of higher frequencies, some trends of shifting of the characteristic frequency bands are recorded. The potential of the obtained results is to complement the knowledge of the emission of modern lighting sources, which can be further used for digital models of these devices and to estimate the impact on the grid under real working conditions.

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%, yang masih 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.

Penelitian ini menganalisis harmonisa transformator satu fasa yang dibebani dengan Motor Arus Searah (MAS) dan penyearah dengan menggunakan pendekatan metode kuantitatif. Tujuan dari penelitian ini adalah untuk mengidentifikasi nilai Total Harmonic Distortion untuk arus (THDi) pada transformator dan merancang filter pasif guna mengurangi tingkat harmonisa apabila tidak memenuhi standar. Hasil penelitian menunjukkan bahwa hasil pengukuran, diperoleh THDi 31,01% pada transformator beban nol, pada transformator dengan beban MAS dengan penyearah setengah gelombang, THDi sebesar 79,35%, dan pada transformator berbeban MAS dengan penyearah gelombang penuh, THDi sebesar 46,40%, yang melebihi standar IEEE 519-2014. Hasil simulasi filter pasif single tuned LC menunjukkan bahwa pada transformator berbeban MAS dengan penyearah setengah gelombang mengalami penurunan tingkat harmonisa dari nilai THDi 79,35% sebelum menggunakan filter, menjadi 1,04% setelah menggunakan filter dan memenuhi standar IEEE 519-2014. Tingkat harmonisa dari transformator berbeban MAS dengan penyearah gelombang penuh, sebelum difilter, THDi 46,40%, namun setelah difilter, THDi 37,98%, masih melebihi standar IEEE 519-2014.
