查询词典 impedance

The existence of fault resistance may add an additional reactive or capacitive component to the impedance seen by the protection.

在双电源系统中，由于对侧系统助增电流的影响，保护测量到的阻抗会偏离故障线路的实际值，从而引起距离保护发生超越或缩短保护距离。

The existence of fault resistance may add an additional reactive or capacitive component to the measured impedance seen by the protection.

距离保护测量到的阻抗由于受对侧系统助增电流的影响会偏离故障线路的实际值，从而引起距离保护发生超越或者缩短保护距离。

Secondly, the discharge characteristics were investigated. As the RF power was switched on and the matching impedance suitably set, a pale-purple glow was initially generated near the wall. With increasing RF power, the pale glow evolved into bright white glow. Analysis of voltage and current wave forms suggested that both the voltage and current wave forms are predominately sinusoidal and discharge cycle was above 100 nanoseconds. Current-voltage curve showed that discharge current increase as voltage increase without any abrupt; The current-voltage phase angle suggested that the plasma evolved from being predominately capacitive to predominately resistive. Discharge mode was essential an abnormal glow discharge plasma.

其次对装置的放电特性进行了分析，从放电的现象看，随着放电功率的提高，放电颜色由开始的暗紫色过渡到亮白色；从电流-电压波形曲线图发现所有的放电电流和电压曲线都是正弦曲线，放电的周期达到上百个纳秒；从电流—电压曲线分析，电流随着电压的增长而增长，并没有发现任何的突变现象；从电压—电流相位角来看，随着电流的增大，相位角基本保持不变，整个电路表现出容性放电性质，但是电阻性成分已经很强，属于反常辉光放电区域。

The results show that in subsynchronous frequencies range the transmission line compensated by the SSSC causes a resonant impedance effect similar to that caused by the fixed capacitors. But the value of the capacitive reactance exhibited by SSSC is smaller than that of the fixed capacitors and the additional resistance component is exhibited by SSSC.
