Analysis and mitigation of harmonic at Perpustakaan Tun Abdul Razak 3: article / Mohd Hanif Abdul Karim

This paper propose the analysis and mitigation of harmonic distortion that have been done in PTAR 3 (Perpustakaan Tun Abdul Razak) at Tower two science and technology, UiTM Shah Alam. There are three main focuses for this project, firstly is to calculate the total harmonic distortion (THD) produce by fluorescent lamps, computers and a combination of both when it connected in parallel. Secondly, this project needs to find out which equipment produces the higher THD between computers and fluorescent lamp at the PTAR 3. Lastly, this project also needs to reduce the THD produced by combination of both equipment’s when it connected together to be lower than 5% to satisfy the IEEE regulation. In order to reduce the THD lower than 5% a passive filter must be installed at the ac source.
