Safety assessment of electromagnetic pulse radiation field of UHV transmission line

In this paper, the safety of the electromagnetic field generated by the pulse current in the human body during corona discharge of UHV AC transmission lines is evaluated. The time domain pulse waveform of positive and negative corona current is simulated by MATLAB, and the pulse current at 10 MHz is extracted by Fourier transform, which is used as the feed input dipole antenna to equivalently replace the electromagnetic field generated by corona discharge. The maximum electric field, the maximum magnetic field and the maximum electric field of the head obtained by simulation are less than the limits of the international standard ICNIRP. The results show that the human body is in a safe state in the corona discharge electromagnetic field.
