The high-tech industry has the characteristics of highly sensitive production equipment and intensive production, and thus has great requirements of stable power supply and good power quality. This study is of a high-tech factory in the CTSP as an example, by building power quality monitoring systems, and thus based on the SEMI F47 standard to analyze the reasons and categories of the voltage sags. The results can be as a reference for installing voltage sag improvement equipment and new high-tech factory and power system planning. Further, installing the voltage sag compensation equipment to improve the loss due to voltage sag is illustrated. In addition, the analysis and comparison of the voltage sag events before and after the establishment of the EHV substation (E/S) in the CTSP show the benefits of the E/S on reducing the voltage sag occurrences and the losses of the production.
