Electric field coupling:Also known as electrostatic coupling,it enters other lines through capacitive coupling.Distributed capacitance will be formed between the two wires,and distributed capacitance will be formed between the printed wires on the printed circuit board,between the turns of the transformer and between the windings.The existence of these distributed capacitances can provide an interference reactance channel for the interference signal,and the electric field interference can enter the system through this channel to form interference.
电场耦合：又称静电耦合，是通过电容耦合窜入其它线路的。两根导线之间会构成分布电容，印制电路板上各印制电线之间、变压器线匝之间和绕线之间都会构成分布电容。这些分布电容的存在可以为干扰信号提供干扰电抗通道，电场干扰就可以由该通道窜入系统，形成干扰。
