Question 21.2: The instantaneous position of a certain Y-connected ac gener...
The instantaneous position of a certain Y-connected ac generator is shown in Figure 21–12. If each phase voltage has a magnitude of 120 V rms, determine the magnitude of each line voltage, and draw the phasor diagram.
The magnitude of each line voltage is
V_{L}=\sqrt{3} V_{\theta}=\sqrt{3}(120 V )=208 VThe phasor diagram for the given instantaneous generator position is shown in Figure 21–13.
