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