Paper Title
Design and Installation of UPS Units for Industrial Three-Phase Power Continuity

Abstract
With the rapid advancements in modern science and technology, electrical systems and equipment have become increasingly diverse and complex. This complexity has also heightened the sensitivity of machines to sudden power fluctuations, making them more vulnerable to failures or interruptions. Such disturbances can disrupt production processes, raise maintenance costs, shorten equipment lifespan, and ultimately reduce profitability and economic returns. One of the most critical challenges faced today is the issue of voltage drops and sudden deviations whether above or below standard levels which can result in significant financial losses. To address this, our project aims to conduct a theoretical study closely aligned with real-world conditions for installing a three-phase UPS unit from the British company Eaton. The UPS includes integrated protection circuits, and we will configure its primary operational settings. Furthermore, the study will clarify the connection mechanism of the UPS with both the public grid and backup generation units to ensure reliable protection of industrial equipment and three-phase machinery across industrial facilities.
