Is sensitivity a feature of relay protection
The sensitivity of the system is the ability of the relay system to operate with low value of actuating quantity. It indicates the smallest value of the actuating quantity at which the protection starts operating in relation with the minimum value of the fault current in the protected. The protective system should be sufficiently sensitive so that it can operate reliably when required. The paper also discusses some practical considerations for evaluating. Dependability is the degree of certainty that the relay will operate correctly: Dependability can be improved by increasing the sensitivity of the relaying system. Engineering use: Relays are used on feeders, transformers, buses, motors, generators, and transmission lines to protect equipment and improve system. Relion protection and control relays for several application reduce complexity.
