>May , · The fastest arcflash relay times range from about less than millisecond to milliseconds. These reaction times are a function of the arcflash relays light sensor input sampling scheme and how the trip output circuit is designed. Avoidance of nuisance is important to a relays sampling scheme.

>Arc fault protection implemented using the arc fault protection relay REA. The arc sensor loop of the relay passes through all the spaces to be protected. Tripping requires a light signal generated by an arc and an overcurrent signal caused by a fault current. Current is measured threephase as A or A secondary current.
