<p>PROBLEM TO BE SOLVED: To provide a search signal return path formation system mechanism and method for forming a loop circuit, where a conductive building structure is connected and utilized partially in the route search of a wire to be searched. SOLUTION: A loop circuit where a search signal flows is formed by a building structure 1 that is grounded and made conductive as a ground conductive path, building ground parts 2a and 2b of the building structure 1, a grounding line 3 that has already been installed in a building and is a wire to be searched, a grounding part 4 for grounding the grounding line 3, a search signal oscillator 5a for oscillating and applying a search signal, and a capacitive coupling part 6a for modeling capacitive coupling being generated by the connection between the building structure 1 and the search signal oscillator 5a. As a result, by utilizing the building structure 1 that is grounded and made conductive even if the ground side of a commercial power supply with a hazard as an electrode is not used, the wire to be searched can be safely and easily searched without requiring an exposure operation of wires other than the one to be searched.</p> |
