Strategies for Reducing Arc Flash Risks in Data Centers

This white paper outlines strategies for mitigating the risks associated with arc flash incidents in data centers, particularly as power densities rise due to advancements in artificial intelligence and high-performance computing. It details five key strategies: implementing safer power distribution designs, conducting arc flash hazard studies, ensuring the proper use of personal protective equipment (PPE), utilizing overcurrent protection devices (OCPDs), and deploying advanced technologies such as remote plug-in actuators and infrared scanning. The document emphasizes the importance of understanding the causes of arc flash incidents, which can result from various factors including equipment failure and improper installation. It also discusses the evolution of power distribution architectures, comparing legacy panel systems with electrical busway systems, highlighting the safety advantages of the latter. The need for regular arc flash hazard studies is stressed, as they help identify hazard areas, ensure compliance with safety regulations, and potentially lower insurance costs. Overall, the paper provides a comprehensive approach to enhancing safety in high-density data centers.
