Abstract :
Contrary to popular belief, generators can fail - not only from short circuits - but also from abnormal electrical conditions such as overexcitation, overvoltage, loss-of-field, and unbalanced currents. When subjected to these abnormal conditions, damage or complete failure of the generator can occur within seconds. In many cases, these failures can be prevented by proper generator protection.
