    負載端電阻低於傳輸線特性阻抗及電源電阻高於傳輸線特性阻抗情況下，當線長為某頻率波長之半波，則輸入端與負載端電壓在該頻率均為最低，在該頻率之半時則電壓均為最高。
  3. Applying relative arithmetic to all kinds of faults and calculating off - line, we can master time - distance relation chart for all kinds of faults. computation indicates : when transmission lines occur faults, the data window of protection algorithm consisting of prefault and postfault data at the same time has important significance. the following methods are useful to achieve the inverse time characteristic : calculating impedance by using flourier in a full cycle, calculating work voltage by using fault component, calculating the torque created by a phase comparator or a magnitude comparator

    實際的計算表明：輸電線路發生故障后，用故障前後的數據同時充滿保護演算法的數據窗，對于快速切除近區故障具有很重要的意義；同時利用故障前後的數據，下述方法可以比較好地實現距離保護的反時限特性：直接用全周傅里葉演算法進行阻抗計算；採用工頻變化量阻抗繼電器進行工作電壓的計算；採用轉矩的思想進行轉矩的計算。
