Abstract:High-altitude electromagnetic pulse may cause damage to electronic equipments through coupling pipeline system.In order to study the effects of high-altitude electromagnetic pulse on overhead pipeline,the electromagnetic field-to-overhead pipeline coupling equations are derived from Maxwell's equations.The coupling equations are solved in frequency domain by applying the Green's functions,and the time-domain waveforms of induced currents and voltages are obtained by using inverse Fourier transform.Finally,the currents and voltages on the pipeline induced by intermediate-time HEMP(E2) based on IEC standard waveform are calculated.
