Data Center Arc Flash and Protection Study

Herndon, VA

BKM provided an arc flash analysis and an overcurrent protection analysis for this Fortune 500 corporate client’s Mission Critical Infrastructure.

Over 290+ buses were analyzed. As part of the protection study, several deficiencies were noted in the system indicating that existing conductors were not properly protected for fault current. New breaker settings were determined as needed to protect the owner’s assets. Comprehensive field surveys were done and data was gathered by BKM and an electrician. Extensive research was performed with product representative, Eaton, and SKM software for modeling equipment not in the SKM library. The study was performed in conjunction with a UPS upgrade design and a critical circuit breaker failure forensic study. Several recommendations were made for the facility to improve its reliability and performance.
