Two identical 1,000 MW generators are operating in parallel supplying the same isolated electrical bus.
The generator output breakers also provide identical protection for the generators.
Generator A and B output indications are as follows:
A malfunction causes the voltage regulator setpoint for generator A to slowly and continuously increase.
If no operator action is taken, generator B output current will…
A. initially decrease, and then increase until the output breaker for generator A trips on overcurrent.
B. initially decrease, and then increase until the output breaker for generator B trips on overcurrent.
C. increase continuously until the output breaker for generator A trips on overcurrent.
D. increase continuously until the output breaker for generator B trips on overcurrent.
