<P>PROBLEM TO BE SOLVED: To provide a low-cost method and a device for suppressing a rise in potential, surely suppressing the rise in the potential of a tower leg by a simple structure such that a loop conductor or a tabular conductor is connected to the periphery of the anchor portion or base portion of the steel tower leg. <P>SOLUTION: In a structure including the base portion 20 buried in the ground and the anchor portion 11 fixed to the base portion 20, the loop conductor 30 or the tabular conductor is connected to the surface of the anchor portion 11 or the surface of the base portion 20, and induced current in a direction canceling lightning current flowing onto the ground from the steel tower leg through the anchor portion 11 or the base portion 20 is conducted to the loop conductor 30 or tabular conductor. Thereby, it is possible to suppress a steep rise in the potential of the steel tower leg 10. <P>COPYRIGHT: (C)2011,JPO&INPIT |
