1 Scope and references
1.1 Scope
1.2 References
2 Objectives and Generator Grounding
2.1 Minimizing damage for internal ground faults
2.2 Limiting mechanical stress in the generator for external
ground faults
2.3 Limiting overvoltages on generator insulation
2.4 Providing a means of generator system ground-fault protection
2.5 Coordinating with other apparatus at generator voltage-level
3 Generator Grounding types
3.1 Unit-connected generation systems
3.2 Common bus generators without feeders
3.3 Generators with feeders directly connected at generated voltage
3.4 Three-phase, 4-wire connected generators
4 Bibliography
Annex A (informative) example of high-resistance grounding
Annex B (informative) resonant grounding of a unit-connected generator
system
Summarizes the general considerations in grounding synchronous generator systems and discusses the factors to be considered in the selection of a grounding class and the application of grounding methods. Guidelines apply to both the large and small generators found in electric utility systems.
