Relt arc flash
WebAFDD (arc flash detection device) is a type of relay that uses current and voltage sensors to detect an arc flash and send a signal to the breaker to trip. AFR (arc flash relay) uses a combination of current, voltage and thermal sensors to detect an arc fault and interrupt the current by tripping the breaker closest to the arc flash. WebThe AF0100 is a cost-effective solution that reduces arc-fault damage by detecting the light from an arc flash and rapidly tripping. Two remote light sensors can be connected to one …

WebMay 1, 2024 · The fastest arc-flash relay times range from about less than 1 millisecond to 9 milliseconds. These reaction times are a function of the arc-flash relay’s light sensor input sampling scheme and how the trip output circuit is designed. Avoidance of nuisance is important to a relay’s sampling scheme. http://m.eaton.com/ecm/groups/public/@pub/@electrical/documents/content/wp005002en.pdf
