phase comparator meaning in English
相位比较器
Examples
- The research of new type 1okv high - voltage phase comparator
高电压相位测量仪 - 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
在综合电路ic1的内部，经过合适的划分，两个频率被送往相位比较仪，这两个频率产生二级振荡器的锁电压。 - 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
实际的计算表明：输电线路发生故障后，用故障前后的数据同时充满保护算法的数据窗，对于快速切除近区故障具有很重要的意义；同时利用故障前后的数据，下述方法可以比较好地实现距离保护的反时限特性：直接用全周傅里叶算法进行阻抗计算；采用工频变化量阻抗继电器进行工作电压的计算；采用转矩的思想进行转矩的计算。
