First Claim
1. A method of using a computer system to provide utility information related to a plurality of underground power line cable segments, wherein a multitude of the underground power line cable segments are connected on opposite ends to different distribution transformers and carry power having a voltage greater than one thousand volts, the method comprising:
- monitoring the impedance of each of the plurality of underground power line cable segments over time;
detecting a change in the impedance of a set of the plurality of underground power line cable segments;
storing in a memory information sufficient for identifying each underground power line cable segment of the set of the plurality of underground power line cable segments for which a change in impedance is detected;
generating a report that identifies the set of the plurality of underground power line cable segments for which a change in impedance is detected; and
outputting the report.
