The sensitivity of relay protection refers to
Sensitivity is the ability to detect small faults, and selectivity is the ability to discriminate faults within the relay's zone of protection. One of the main requirements to relay protection is the sensitivity requirement, which implies consistent tripping during the short circuit (s c) events in the protected zone. The sensitivity should be sufficient to ensure reliable protec-tion during s c at the end of its specified zone under. Dependability refers to a relay operating when expected to, while security means a relay does not operate when not expected to. The protected zone is defined and limited by different things depending on the protection function. -
