| dc.description.abstract | NonJinear load has non-sinusoidal wave form because it has been distorted by
harmonics culrent, non linear load in personal computer (PC) one the causes of
harmonics which can cause the quality of electric power to be worse. The research used
simulation method of single tuned filter as the filter used to reduce harmonics caused by
PC dual core using 15 inch LCD monitor and printing machine. By using measurement
device, power quality analyzer fluke SW43W, it is found that PC of D brand, which has
the biggest IHDi in the second order, is 0.469 ampere, the fifth order is 0.360 ampere,
the seventh order is 0.226 ampere, and the ninth order of 0.103 ampere. The Result of
the simulations, using passive single tuned filter, shows that the decrease of harmonics
currcnt value in thethird order is 0.331 ampere, the fifttr order is 0.0254 ampere, the
seventh order is 0.159 ampere, and the ninth order is 0.072 ampere, there is also the
decrease of harmonics current in other orders. The passive single tuned filter being used
with C value is 9,99 pf, L value is 0,021 H, and R value is 0.46 which can reduce [HDi
from l0% - l5o/o whith the decrease of IHDi order up to the 49fr order value. The bigger
the value of the used capasitor the closer the IHDi wave to sinusoidal, and it even
becomes sinusoidal. | en_US |
