This paper covers the overall view on power quality analysis in the semiconductor industry. The increasing number of power electronic device used especially in the industry has raised the awareness of power quality problem. Normally, this device creates the non-linear loads which will effect to the electrical power system. This paper covers the aspect of power quality disturbance by giving definition, source and the effects of this disturbance to the electrical power system. The objective of this project is to do analysis on power quality monitoring data from one of the semiconductor industry. On-site power quality monitoring data had been done before. Specific equipment had been used to get the actual reading from the plant. By using PQSCADA software, a software that visualizes the graph analysis from each measurement data to determine any power quality disturbance in the electrical power system. The findings will give better insight for the consumer to know the power quality that they have and to predict the future performance of the equipment. The author analysis based on the power quality standard. Based on the result analysis, the author had found power quality disturbances occurring in the system, which is voltage sag and harmonic distortion. These two types of power quality disturbance always occur in the electrical power system. Power quality problem can be solve by add in and installing UPS and harmonic filter for better performance in the electrical system.
