This project used PIC24FJ64A004 and Bonus Part MCP6S26. mcp2030, mcp1700 The Cable Tracer is device to detect underground cables. It was designed and tested on un-energized electric power cables but could be used on any underground cable. A 125 Khz signal is injected into the underground cable from Signal Generator.

The output voltage level of the Signal Generator will effect how deep of a cable can be detected. The Generator used in my setup was a HP 3310B which has up to a 30 volt output. I was able to sense cables buried around 2 feet with only a 10 volt output. The Circuit Breaker was turned OFF in the Panel box and the Signal Generator output was connected to the cable.
