Relay protection setting sensitivity verification - SMB AI-Systems & High-Speed Interconnect [PDF]
In order to ensure the requirements of selectivity, rapidity, sensitivity and reliability of relay protection devices, users with high requirements for power supply reliability and users of 60kV and

Digital and numerical protection relays use software for relay protection and measurement functions. This software must be properly tested to make sure that the protection relay follows all specifications

To effectively perform its role, relay protection must be accurately configured with appropriate settings. Settings verification, also known as relay testing or commissioning, is a process

To avoid relay mal-operation, set Slope 2 as high as possible. Normally, a high Slope 2 setting causes slow tripping for evolving faults (external-to-internal faults).

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 relay
