Upon loss of field excitation of a generator operating in parallel with others, what must be done? |
A) The parallel-connected generator which has suffered the loss of field excitation must be immediately disconnected from the bus by tripping its circuit breaker. |
B) The parallel-connected generators still producing a voltage must have their fields over-excited to compensate for the loss of field excitation of the one generator. |
C) The parallel-connected generator which has suffered the loss of field excitation must have its prime mover immediately stopped. |
D) The parallel-connected generator which has suffered the loss of field excitation must have its prime mover immediately reduced to idle speed. |
