Sensitivity
The sensitivity of 7SR46 Argus Relay is 0.8 ⋅ I
phase current) in 3-phase. This minimum phase current is necessary for the healthy functioning of the relay.
The following graphs shows the sensitivity of the relay, In the absence of auxiliary power supply, the sensi-
tivity of the relay is the minimum phase current required for the relay to energize, detect a fault, and trip as
per the configuration.
