B&N completed a power system study and arc flash hazard analysis following recent power system upgrades completed by contractor EG Middleton, Inc. at Vinings Landing Marine Center in Norfolk, Virginia.
The hazard analysis involved determining the maximum energy electrical equipment might release during an arc flash event. An arc flash is a sudden burst of energy that can happen with electrical equipment. It occurs when electricity jumps through the air instead of following its normal path. This release creates intense heat, bright light and a powerful blast that can be dangerous for people working near electrical equipment.
Our engineers conducted a site visit for data collection, completed a short circuit study to determine available fault currents at various system points, completed a Protective Device Coordination Study and calculated the collected data to determine incident energy levels and arc flash boundaries.
B&N provided the client with a final report with recommendations for improving safety and reducing arc flash hazards. The client used this to ensure the proper installation of warning labels that will inform future maintenance personnel as they work on or near electrical equipment.
