Please show as much working as possible and comment where possible.
The figure in attachment represents a high-voltage transmission line. With the receiving end on open-circuit, the relationships between the sending end voltage and current and the receiving end voltage are given by the equations in the attachment.
Given the parameter values in the table in the attachment, and an open-circuit voltage measured as 88.9 kV, calculate the open-circuit power absorbed from the supply by the transmission line.
This posting contains the solution to the given problems.
