Conductor Identification Using Acoustic Signal Method

Electrotechnical services spend a significant amount of time on cable tracing and conductor identification operations. Although the operation seems an easy job deeply researched topic, it may turn out to be time-consuming due large quantity unidentified conductors (cables) certain stipulation that should de-energized have uninsulated parts. This paper proposes method based use acoustic signal as carrier, making possible facilitate process significantly speed up process. For proposed method, mathematical modeling sound propagation in insulation is detailed. The pressure level subject identified length, cross-section type was calculated basis model. performed calculations revealed remarkable capabilities for identifying comparison with other methods. So, difference only 3.65% distances from point source 5 m 100 m, 0.42% between minimum maximum cross sections (1 mm2 25 mm2, respectively) 0.22% polyethylene PVC insulations. prototype device assembled way practically confirmed theoretical research average percentage discrepancy about 1.44%. In addition, analyzes constituents justify application by
