Generator Protection

EGP Generator protection:

Effective protection of generators against internal and external faults requires that a wide variety of protective devices be deployed.

Generator differential protection covers the internal faults like short-circuit fault, interturn and interwinding faults or phase-earth-phase faults and serves as the primary protection.

The time overcurrent protection constitutes the reserve protection for the generator and can also be used for the detection of external faults, such as short circuits and overload, for example. Earth-fault occurrences are detected with the stator-earth fault protection. The investigation of reverse power and unbalanced load protection as well as overvoltage/undervoltage protection concludes the experiment series titled “EGP“ on generator protection.
