Sensitivity refers to the sensitivity of a relay protection device
Sensitivity in protective relays refers to: The minimum fault current (or power, voltage, etc. ) that the relay can reliably detect and respond to. Based on simple examples of the generator-transformer unit protection from symmetrical short circuits, it was shown that the sensitivity factor is not a sufficiently objective measure of sensitivity of the. Selectivity is a mandatory requirement for all protection, but the importance of it depends on the application. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. Only the effected parts of the power system shall be disconnected. Necessity of speed in relaying. A relay is said to be dependable if it trips only when it is expected to trip.

Relay protection anti-pumping device
The anti-pumping relay is a circuit breaker auxiliary relay that is used to protect the circuit breaker from multiple closing commands. Even we can run the power system without of these relays. If the TNC switch fails (Trip normal close) or there is any problem with the CB (circuit breakers) closing circuit, the continuous CB (circuit breakers) close command can be extended to. Why is the Anti-Pumping Relay Used? A circuit breaker is a very important equipment for a high-voltage power system.
