An arc flash study is the evaluation of a facility to determine hazards in relation to the electrical system. The on-site study results in arc flash equipment labeling, fault current and coordination analysis, recommendations for improvement, and the required personal protective equipment needed to be worn.
Power quality studies identify power quality problems effecting critical equipment and facility operations. These can include nuisance breaker tripping, random shutdowns, or brown-out events. Power factor problems may include excessive Utility Company rates if not corrected or remedied.
A short circuit study determines the fault current at various locations throughout the electrical distribution system, and if the electrical equipment is rated properly for the fault current it would experience in the event of a short circuit. For the equipment to be properly rated, its interrupting rating needs to be greater than the fault current it is seeing.
System ground studies determine proper ground conductor sizing and connections. High resistance connections reduce the grounding effectiveness and proper breaker operations to protect life and property.
Breaker coordination studies are done to minimize interruption of electrical services to other areas of the power system, the breaker or fuse closest to the short circuit operates first to clear the fault. This is achieved by completing an engineered coordination study.
