A 30-kW, 240-V generator is running at half load at 1,800 r/min with an efficiency of 85 percent. Find the total losses and input power.
14.11 A self-excited DC shunt generator is delivering 20 A to a 100-V line when it is driven at 200 rad/s. The magnetization characteristic is shown in
Figure P14.11. It is known that Ra = 1.0 Q and
Rf = 100 Q. When the generator is disconnected from the line, the drive motor speeds up to 220 rad/s.
