Two identical 1,000 MW generators are operating in parallel, supplying all the loads on an 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 setpoint for generator B to slowly and continuously decrease.
If no operator action is taken, the electrical current indication for generator B 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. decrease continuously until the output breaker for generator A trips on overcurrent.
D. decrease continuously until the output breaker for generator B trips on reverse power.
