Electrical Engineering · Power Systems
Let I, R, XL, VR, and cosφR represent the line current, line resistance, line inductive reactance, receiving end voltage, and load power factor of a transmission line, respectively. If the receiving end voltage is greater than the sending end voltage (Ferranti effect), identify the correct condition for a leading load power factor.
- 1IR cosφR >> IXL sinφR
- 2IR cosφR < IXL sinφR✓
- 3IR cosφR > IXL sinφR
- 4IR cosφR = IXL sinφR
Correct answer
IR cosφR < IXL sinφR
