| Abstract: | The utilization of more and more long-distance and large-capacity DC transmission circuits has made rather remarkable influence on magnetic survey in near-circuit areas. This paper describes the structure of the DC transmission circuit, characteristics of circuit magnetic fields and their effects on the ore-prospecting magnetic survey. The features of DC transmission circuit magnetic field in the magnetic map are also discussed. Some examples illustrating the effects of the DC transmission circuit are also given in this paper. |
