Abstract :
The use of non-linear loads can cause harmonics in both current and voltage in the electrical system. Non-linear loads are generated from the use of electrical equipment such as computers, air conditioners, semiconductors, and other switching electrical equipment. Harmonics that exceed the standard will have an impact on the quality of the power supplied. The use of Single-Tuned passive filters aims to reduce harmonics both current and voltage in the electrical system of the Samarinda State Polytechnic Architecture Building. This research explains how to calculate the Single-Tuned filter and how to input the calculation results into the ETAP software used to simulate the effect of using a Single Tuned filter to reduce harmonics. In this study, it is known that the use of a 5th-order Single-Tuned filter using ETAP software can reduce the THDi value of phase R from 80.43% to 6.27% where based on IEEE 519-2014 standard THDi value for SCRatio 100-1000A is 15%. The IEEE 519-2014 standard for THDi of 15% is obtained by calculating ISC and IL first.
