Hazards of Single-Phase Arc Flash

Hazards of Single-Phase Arc Flash

This article presents different methods for assessing the hazards of high- and low-voltage 1-phase equipment. One common question being asked is how to determine the hazard level associated with 1-Phase (1-P) Arc Flash (AF) incidents. There is very little information about this type of circuit in the available guidelines such as CSA Z462-08, NFPA 70E 2009 & IEEE 1584 2002. If the right risk level is not properly determined, we run the risk of over-protecting or under-protecting personnel that are working on this type of electrical system. The objective of this article is to present different methods for assessing the hazards of high and low voltage 1-P equipment, and to justify the results taking into consideration the behavior of arc faults at different voltage levels.
