Two identical 1,000 MW generators are operating in parallel supplying the same isolated electrical bus ___

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:

Generator-PG--53

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.
