SynchroGrid performed an arc flash analysis on the electrical distribution system for a wind farm operated by Pattern Energy. The study was executed to determine the incident energy levels for 500, 34.5,  0.69 kV equipment, and 240 V AC Panels & 125 DC Panels. Arc-flash hazard analysis was performed using ETAP 18.1.1 software. We made arc flash mitigation recommendations when the incident energy exposures were greater than 40 cal/cm2 as mandated by NFPA 70E.


The Occupational Safety and Health Administration (OSHA) requires employers to protect employees from electrical hazards which includes arc flash. OSHA looks to the prescriptive-based requirements of NFPA 70E to fulfill the performance-based requirements included in its standards. NFPA 70E outlines the safety processes necessary to reduce injuries that can result from being exposed to electrical hazards. 


SynchroGrid can provide you with arc-flash hazard identification and mitigation such that the facility complies with NFPA 70E.
