In a salient pole synchronous machine, neglecting armature resistance (Ra = 0), the excitation voltage E0 for generating action is given by which relation?

Verified Solution4 OptionsUpdated: October 2026👁️1 View

1E0 = V cos(δ) - IdXd
2E0 = V cos(δ) + IdXd✓
3E0 = V cos(δ) - IqRa - IdXd
4E0 = V cos(δ) + IqRa - IdXd

Correct answer

E0 = V cos(δ) + IdXd
