Dangerous Voltages due to Direct Lightning Strike into the Communication Tower
Journal of Communications Software and Systems, 2007 This paper presents a novel technique for computing dangerous voltages due to direct lightning strike into the communication tower and associated earthing system, which is based on the use of the well-known ATP-EMTP software package.

Gaoya dianqi, 2017 护套交叉互联双端接地电缆中,3段电缆长度不均等,或电缆排列方式不对称,均会导致金属护套中产生环流。文中分析了排管敷设的单回路交叉互联电缆金属护套感应电压相量和,采用EMTP模型仿真不同的电缆分段长度差下的金属护套环流,得到EMTP仿真数据样本,用来拟合金属护套环流估算公式,最后将拟合的估算公式计算值与EMTP仿真数据进行对比,检验了估算公式的适用性。此外,还分析了不同排列方式感应电压相量,提出并验证了在不等长分段电缆中,采用恰当的混合排列方式可以降低金属护套环流。

Gaoya dianqi, 1988 一、引言 变电所防止雷电与操作过电压中,GIS的保护性能在许多重要方面与敞开式的变电站不同。传统变电站的绝缘水平主要取决于变压器的保护物——避雷器的正确选择及它们的安装位置;它的空气绝缘的强度可以自动恢复,开关可以耐受如绝缘子或套管闪络这样的故障。而GIS的绝缘不具有自动恢复的这个特性,在遭受过电压时,故整个GIS系统(母线,断路器,隔离开关和接地开关等)必须得到全面的保护。另外,架空线的进线段到GIS开关之间的母线也同样需要保护。GIS装置中 ...
