Description
Summary:The purpose of this thesis is to present the importance and affects of grounding and harmonics to the quality of power. In this case, data center is referred as a case study for the analysis of grounding and harmonic. These power quality issues are very important in data center where it might cause severe failure operation systems. For the investigation of the quality of the power in data center, electrical disturbance log is done to examine the quality of grounding and characteristics of harmonics profiles in the data center. The power monitoring instrument used was Fluke 1750 Recorder and the data recorded was analyzed by using Fluke 1750 Analyze.. The power quality conditions of the data center significantly depends on the every aspect in electrical system such as voltage, current, frequency, power, power factor and so on. As the result of this analysis, the grounding conditions used in the data center was found to have no signs of severity in power quality conditions. However, there were some issues of improper wiring and grounding found in the data center. This will be discussed in this thesis. On the other hand, the harmonic distortion in data center were discussed in terms of the source of harmonics and effects of harmonic on the performance of data center. In order to identify the cause of such orders of harmonics in this system, the most non linear load is identified. Therefore, some recommendations and mitigations of the harmonics were discussed.
