Final answer:
The statement is true as VSWR can appear more favorable at the receiving end due to multiple reflections, giving a false impression of higher efficiency. Power loss in transmission lines is minimized by keeping current low and using higher transmission voltages.
Step-by-step explanation:
The statement about VSWR (Voltage Standing Wave Ratio) giving an illusion of having an efficiency of power transfer that is much better when measured at the receiving end compared to the sending end is true. This occurs because, at the receiving end, multiple reflections can cause the standing wave pattern to appear less pronounced, suggesting a better match than actually exists. This phenomenon can misrepresent the actual efficiency of power transfer along the line.
To understand power losses in transmission lines, we look at the relationship Plost = Itransmitted2 Rwire and Plost = Itransmitted Vtransmitted. To reduce power lost due to transmission, current (I) should be kept low and voltage levels should be high, contrary to the examples provided. High transmission voltages, often in the range of hundreds of kilovolts, are used to minimize losses for long-distance power transmission.
