The induced voltage on underground pipelines is a critical parameter to consider for equipment and personnel safety in the field. However, in the real life, such induced voltage estimation on pipelines is difficult especially at the transmission line planning and routing stage. In this article, several factors affecting the induced voltage on underground pipelines due to inductive coupling with nearby transmission lines are investigated. These factors include the angle and separation distance between transmission lines and pipelines, the length of transmission lines and pipelines, and the soil model. A peak induced voltage calculation formula as the function of the angle and separation distance is derived through surface fitting of simulation data. It is proved in the article that other factors, such as the length of the transmission line and the soil model types, do not have significant influence on the peak induced voltage values on underground pipelines.

由于与附近传输线的电感耦合而影响地下管道感应电压的因素研究

地下管道上的感应电压是现场设备和人员安全需要考虑的关键参数。然而，在现实生活中，这种管道感应电压估计是困难的，尤其是在输电线路规划和布线阶段。在本文中，研究了由于与附近输电线路的感应耦合而影响地下管道感应电压的几个因素。这些因素包括传输线和管道之间的角度和间隔距离、传输线和管道的长度以及土壤模型。通过仿真数据的曲面拟合，推导出峰值感应电压计算公式作为角度和间隔距离的函数。文章证明，其他因素，
