surge impedance

基本解釋

Tower surge impedance is an important parameter for lightning protection design, but its value is not well determined.
桿塔波阻抗是防雷設計中的一個重要參數(shù)，國內(nèi)外對這一問題一直未能很好地解決。
According to the property that the surge impedance relay is realized by the ratio of voltage and current travelling waves, the relay's algorithm based on wavelets is present.
針對波阻抗方向繼電器利用初始電壓和電流行波的比值構成的特點，提出了基于小波變換的繼電器算法。
The reflection and refraction of traveling wave are quite complicated at the sheath-crossing point of high voltage power cable, due to its remarkably noncontinuous surge impedance.
高壓電纜的金屬護套交叉互聯(lián)導致行波在多個波阻抗不連續(xù)點產(chǎn)生了復雜的折反射行為，這對高壓電纜線路的行波故障測距產(chǎn)生很大的影響。

Power lines are extremely hostile places for data signals, with high levels of electronic noise and an obstacle course of transformers, surge arrestors and splices that create a huge impedance to the free flow of high-frequency signals.
