SUMMARY
The Ferranti effect describes the phenomenon where the receiving end voltage of a transmission line increases, particularly in open-circuit conditions, due to the line's capacitance. The discussion clarifies that the capacitive current leads the voltage by 90 degrees, which is counterintuitive since inductors typically cause a lag. The power in this scenario is derived from the voltage multiplied by the current, which remains zero in an open circuit, indicating that the increase in voltage does not require a corresponding increase in current. The references provided include detailed explanations of these concepts, emphasizing the relationship between voltage, current, and phase angles in electrical circuits.
