| Abstract: |
Accurate location of buried cables is crucial for future application of trenchless technologies in urban areas. This paper describes an experimental study on detection and location of underground power cables using magnetic field measurement. To do this, a measurement system is designed to be able to measure the magnetic field of an underground power cable at a number of points above ground. It was constructed using battery powered data acquisition modules connected to a coil array, and controlled by a laptop. The experimental investigation has been carried out in a university car park, where the university’s utility map shows an isolated power cable. The results shows that the measurement system and cable location method predict a reasonable position of target cable. |
