Abstract
LHE lights produce harmonics that disrupt the electric power system. The harmonic effect generated is caused by the use of non-linear electrical electronic components. Non-linear loads produce a distorted capital wave current and result in the formation of waves at a frequency of round multiples of the fundamental frequency. Based on the negative impact caused by LHE lamps, it is necessary to conduct research by designing filters to reduce the THDi percentage generated by the LHE load. The study was conducted by installing a RC low pass filter on the LHE load. The research was conducted by measuring to obtain data from four (4) LHE lamps which were measured using a harmonic measuring instrument. The data obtained in the analysis to find out the THDi size that must be adjusted to the IEEE Standard. Research by using a low pass RC filter with the results of the measurement of the first light (1) the THDi percentage obtained is 60.22% decreased to 4.33%, the second lamp (2) obtained the THDi percentage from 84.44% decreased to 3.66%, third lamp (3) obtained THDi percentage from 72.20% decreased to 3.48%, and fourth lamp (4) obtained THDi percentage from 62.40% decreased to 4.43%. The harmonic reduction results that occurred were quite significant ranging from 55.89% to 80.78%. This low pass RC harmonic filter design has succeeded in reducing Total Harmonic Distortion according to the frequency set (cut off frequency) of 150 Hz in order 3.
