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。 -
Inside the integrated circuit ic1, after suitable divisions, the two frequencies are sent to the phase comparator that generates the lock voltage of the secondary oscillator
在綜合電路ic1的內部，經過合適的劃分，兩個頻率被送往相位比較儀，這兩個頻率產生二級振蕩器的鎖電壓。 -
Rc and other relaxation oscillators just will not do since amplitude noise in whatever circuit functions as a comparator will appear as phase noise on the output signal
Rc諧振器以及其它一些張弛振蕩器不能滿足要求，這是因為它們的核心是電壓比較器，需要利用電壓信號的波動（噪聲）來獲得穩定的輸出，這種波動就構成了時鐘的抖動。
