| Abstract: | Data centers are specialized facilities used to store computer systems, servers, voltage-sensitive devices, and associated components such as storage systems and networking equipment. Equipment installed inside data halls mostly is voltage-sensitive devices. A transient overvoltage or overcurrent will be harmful to that equipment. The demand for Artificial Intelligence (AI) will continue to climb, with infrastructure designed to support high-density GPUs and advanced AI application data center. The power density of data centers will increase depending on the development of AI. People more rely on the convenience provided by AI and the internet. Data centers become more important to human live day by day. Lightning is an unpredictable natural phenomenon. Its variability in terms of current, voltage, duration and waveform are difficult to estimate accurately. Induced lightning surge contains the same characteristics of lightning strike, high frequency with large power in terms of current or voltage. If the induced lightning surge direct connect to the data hall equipment, the consequence will be unimaginable. Malfunction of data hall is the basic consequence of direct impact from lightning surge. Data losses of bank or government will result impact to public and society. The costs associated with downtime are not limited to direct financial losses. It also encompasses the expenses related to restoring services. A protection strategy of lightning surge aims to protect voltage-sensitive equipment inside data hall from lightning induced surge. The strategy contains three components, including the protection of electrical system by surge protection devices, lightning protection system of the building and plantroom arrangements to reduce the impact from direct lightning strikes. |
