In order to study the voltage of the terminal load for twisted pair network coupled with lightning electromagnetic pulse field

the tree-twisted pair network was irradiated. The voltage of terminal load and response law were accessed by changing waveforms of lightning electromagnetic pulse field

and the angles between twisted pair which formed network and terminal loads. It is found that the faster the rising part of lightning electromagnetic field waveforms is

the greater the induced voltage of the terminal load will be

and the pulse width has little effect on induced voltage. The induced voltage of the terminal load linearly decreases as the angles between twisted pair increase

but it does not change the waveforms of induced voltage. The induced voltage of the terminal load linearly increases firstly and then levels off with the increase of tested resistance.
