Output
Output
Load is equal to an over excitation generator.
NOTE:
1. Input active power, genset or mains sends active power to load.
2. Output active power, load supplies power to generator or mains.
3. Input reactive power, generator or mains sends reactive power to load.
4. Output reactive power, load sends reactive power to generator or mains.
