Explanation:
When a traveling wave reaches the far end of an overhead line, it can either get reflected back or get absorbed by the load at the far end. In this scenario, if the traveling wave does not result in any reflection after reaching the far end, it means that the far end of the line is terminated into a resistance equal to the surge impedance of the line.
Surge Impedance:
Surge impedance is the characteristic impedance of a transmission line when it is infinitely long. It is given by the formula:
Zs = √(L/C)
where Zs is the surge impedance, L is the inductance per unit length, and C is the capacitance per unit length of the line.
Explanation:
When a traveling wave reaches the far end of the line, it encounters the termination impedance. If the termination impedance is equal to the surge impedance of the line, there will be no reflection of the wave. This means that the wave will be completely absorbed by the termination impedance without any energy being reflected back.
Open Circuit:
If the far end of the line is open-circuited, the termination impedance becomes infinite. In this case, the traveling wave will be completely reflected back towards the source.
Short Circuit:
If the far end of the line is short-circuited, the termination impedance becomes zero. In this case, the traveling wave will also be completely reflected back towards the source.
Terminated into a Capacitor:
If the far end of the line is terminated into a capacitor, the termination impedance becomes purely capacitive. This will result in a partial reflection of the traveling wave.
Terminated into a Resistance equal to Surge Impedance:
When the far end of the line is terminated into a resistance equal to the surge impedance of the line, the termination impedance matches the characteristic impedance of the line. This results in complete absorption of the traveling wave without any reflection.
Conclusion:
In this scenario, if the traveling wave does not result in any reflection after reaching the far end, it indicates that the far end of the line is terminated into a resistance equal to the surge impedance of the line.
