Design and monitoring of a large data center lightning protection system

The number of built objects of large data centers (DCs) rapidly increasing. High quality protection of equipment and devices and, above all, the services that the DC provides, becomes imperative. The application of DC object protection measures against lightning is becoming more and more effective. In this paper are explained methods for implementation of lightning protection system based on international standards and solution that separate bonding mesh in the form of internal Faraday cage from conductor system and earth termination system realized in the form of external Faraday cage. By continuously measuring values of essential parameters, data processing and information storing, as well as using computer network of the DC itself and existing monitoring and management system, enables real-time lightning protection system condition visibility.
