“…The tests required for this class are defined in the tables 1, 2 and 5 of [4]. Besides the F3 class not requiring high precision it was also demonstrated that a light Flickermeter can attend to the requirements demanded by class F1 [14].…”

This study presents the development and implementation of an alternative Flickermeter based on a low cost embedded electronic system. The development of this new device is based on the original Flickermeter proposed by the IEC 61000-4-15, but with important modifications added. These modifications allow for direct quantification of light variation, in such a way, so as to eliminate the effect associated with the different lamp technologies available through the correct quantification of flicker severity. In order to achieve this objective blocks 1 and 3 of the original IEC Flickermeter were altered and block 2 was completely eliminated. The implementation of a low cost embedded electronic system represents the differential of the developed system in relation to equipment currently available on the market, which is based on solutions of a more elevated cost. The developed prototype was appropriately tested and thus provided encouraging results. In addition, the article also presents an analysis that refers to the susceptibility of lamps manufactured upon the same technologies to flicker, such as compact fluorescent and LED lamps, widely used nowadays for substituting traditional incandescent lamps.

“…In Block A the illuminance signal is normalized, in order to make the measurement independent from the illuminance level. In Block B the demodulation process is completed as it is done in the IEC flickermeter, but with the weighting filter modified as described in [12], to remove the dependence from the incandescent lamp. Block C and D are identical to the IEC flickermeter's block 4 and 5, providing the instantaneous flicker sensation (P inst ) and the short-term flicker values (P st ), respectively.…”

“…The light flickermeter used in the present work is a highly accurate flickermeter, which meets all the requirements of the flickermeter described in IEC 61000-4-15 [9] and that can be validated as a Class-F1 flickermeter. The light flickermeter is implemented as described in [12].…”

“…In order to do that, a large set of Compact Fluorescent Lamps (CFLs) and Light Emitting Diode (LED) lamps, covering a broad range of electric power, have been tested. A light flickermeter ( [8], [12], [13]) has been used to measure their light output response when the supply voltage is affected by RVCs. The study allows to achieve two main goals.…”

Rapid Voltage Changes (RVCs) are one of the Power Quality disturbances that are recently receiving a lot of attention from the point of view of international standards. However, although they can cause or contribute to flicker, IEC 61000-4-15 only addresses periodic amplitude fluctuations and more effort is needed to regulate the occurrence of RVCs, according to their effect on flicker perceptibility. Alongside, flicker perception is challenged by the integration of modern lighting technology, whose response is different from the traditional incandescent lamp. This paper studies the connection between the increasing importance of RVCs and the evolution of illumination technologies. Sensitivity of modern lighting technologies to RVCs is studied by measuring flicker with a high precision light flickermeter. A large set of modern lamps is tested and the relationship between RVCs parameters and flicker perceptibility is analyzed.

“…On the other hand, the replacement of incandescent lamps with more efficient lighting technologies gave rise to poor correlation between measured flicker levels and customers complaints [10,11]. To address this latter problem, many researchers worked to develop new instruments, with the objective of assessing flicker due to modern lighting technologies [12][13][14][15][16]. In addition, a lot of effort was put into studying the sensitivity of the new lamps to voltage fluctuations.…”

Flicker of Modern Lighting Technologies Due to Rapid Voltage Changes

et al. 2019

The purpose of the present paper is to evaluate the sensitivity of modern lighting technologies to different types of RVCs. In order to do that, 27 modern lamps—mainly LED—have been subjected to real RVCs and their response has been assessed. The detection of RVCs on the grid has been performed according to the IEC 61000-4-30 detection method, while the response of the lamps has been measured with a light flickermeter and characterized using the instantaneous flicker perception, as defined in IEC 61000-4-15. The obtained results show a high dispersion in the response of the modern lighting technologies and high values of flicker perception, although with a lower sensitivity than the incandescent lamp. The results led the authors to propose the definition of a new immunity test to be added to the lamp immunity protocol IEC TR-61547-1, to ensure that newly produced lamps cause limited irritation to grid users.
