电力工业的一个主要问题是配电线路老化。通过涡流检测或在配电线路通电时测量配电线路周围的磁场，可以对配电线路的裂缝进行无损检测。通过实验室实验，我们研究了这些方法中的每一种，即涡流测试和磁场在导线和配电线周围的分布。结果表明，这两种方法都是检测配电线路劣化的有效手段。
A major problem in the electric power industry is distribution-line degradation. Nondestructive detection of cracks in a distribution line may be possible through eddy-current testing or measurement of the magnetic field around the distribution line when it is energized. We have examined each of these methods, eddy-current testing and distribution of the magnetic field around a conducting wire and around a distribution line, through laboratory experiments. Our results indicate that both methods provide an effective means of detecting distribution-line deterioration.
