管道与电力线交叉时,由于感应二次电压而使管道防腐层老化。
When intersected with electric line, the coating of the pipeline will be aging due to secondary voltage inducted.
如果电力线与通信线之间的互感系数已经知道了,那么计算它们之间的电磁感应效应是很容易的。
The inductive effects between power lines and telecommunication lines can easily be calculated if the mutual inductance has been known.
