A main generator output breaker is about to be closed to connect the main generator to the power grid via the main transformer.
The main transformer voltage and frequency are as follows:
Voltage = 20,000 volts
Frequency = 60.0 Hz
Which combination of main generator voltage and frequency will ensure that the main generator will immediately supply real (MW) and reactive (MVAR) electrical power to the power grid when the main generator output breaker is closed?
A. 19,950 volts; 59.9 Hz
B. 19,950 volts; 60.1 Hz
C. 20,050 volts; 59.9 Hz
D. 20,050 volts; 60.1 Hz
