摘要：Long conductors of all types on Earth's surface are subject to disturbance and disruption by telluric currents (currents that flow within the Earth or on its surface) induced by space weather events. Attention is most often paid to the effects that these currents can produce in electric grids. After all, if an electric power system is disrupted, many other modern infrastructures that depend on the secure and continuous supply of electrical power will also be affected.
