the transfer of high-speed rail and aircraft is more convenient.
For this reason, this research in this article is more conducive to
meet the transfer needs of high-speed train and civil aviation
for passengers and can provide a reference for airports and
railway departments.
Conclusion
Fig. 7. Curve of R with distance x at different site.
In this article, we measure the electromagnetic interference
field intensity of pantograph-catenary arc. Moreover, we determine
the protection distance of the GS based on the test
data, which is 6794 m of GS when the railway running parallel
to the runway. Finally, we compare the differences between
protection distances calculated by our method and by other
existing methods, and we obtain more accurate calculation
results. The research in this article will provide some information
to railway and airport departments in planning and site
selection for reference, which is more conducive to the transfer
needs of high-speed train while aimed at guaranteeing the
safety of civil aviation.

this conclusion. Because the field intensity used in the existing
methods are much smaller than the actual field intensity, larger
protection distances are required to guarantee adequate protection
rates. Consequently, our method is more accurate than
existing methods. The shorter protection distance means that
