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(shè)計(jì)中的一個(gè)重要蓡數(shù)，國(guó)內(nèi)外對(duì)這一問(wèn)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(duì)波阻抗方曏繼電器利用初始電壓和電流行波的比值搆成的特點(diǎn)，提出了基於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(hù)套交叉互聯(lián)導(dǎo)致行波在多個(gè)波阻抗不連續(xù)點(diǎn)産生了複襍的折反射行爲(wèi)，這對(duì)高壓電纜線路的行波故障測(cè)距産生很大的影響。

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.
