Abstract
This research aims to determine the performance of a passive C-type filter simulated with computer software in reducing harmonic currents. The object of research in this study is a laptop, where laptops are currently no longer tertiary needs but have become primary needs, especially in education circles. Universitas Negeri Medan is one of several campuses in Indonesia which is a means of learning process for students in improving their competence in order to get a decent job. The laptop itself is equipment that is included in the nonlinear load category, where the nonlinear load is a harmonic current generator. From the results of harmonic current measurements on the laptop load, the harmonic current obtained exceeds the standard permitted by the IEC 61000 3-2 standard, which is 0.13 A. To overcome the harmonic current that causes this nonlinear load, a type C passive filter is used. The IEC 61000 3-2 standard states that laptops are included in the class D category because they are equipment that has a power below 600 W. After the simulation, a reduction in harmonics was obtained in the seventh order so that the large harmonic current became 0.07 A, therefore it can be concluded that the seventh order harmonic current was successfully reduced by the type C passive filter and has complied with the IEC 61000 3-2 standard.
