Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDF- During the no-load condition, the current flowing is only charging current due to line capacitance. It increases the capacitive var in the system.
- Since the line is under no load the line inductance will be less. Therefore, the capacitive var becomes greater than inductive var during no load or light load condition.
- Due to this phenomenon, the receiving end voltage becomes greater than the sending end voltage. This effect is also called the Ferranti effect.
