ABSTRACT
In general, protection engineering requires a high degree of technical expertise, as well as experience with the nuances of the operation of generating stations. Practicing protection engineers also assume significant responsibilities. They are concerned about employees’ personal safety and try to protect the apparatus and not cause nuisance tripping or unnecessary outages. In essence, they are performing a balancing act, doing their best to leave themselves in a defendable position. They also need to make sure that their settings coordinate with other relays or protective functions. The suggested settings in this chapter, as well as the next on generator protection, have withstood the test of time and have proved to be very effective at coordinating, protecting electrical apparatuses, and mitigating nuisance tripping.
