WHY GENERATOR PROTECTION?

  • Unnecessary tripping of Generators is undesirable (production losses, black-out, startup time)
  • Not tripping and damaging the machine would be expensive (to repair)

The fault current in the faulted generator does not stop when the Generator is tripped or the field breaker is tripped. The flux/energy stored in the field will continue to supply fault current for several seconds
