Abstract
Apparatus for identifying faults within electrical power cables is provided. The apparatus allows a user to detect faults in cables regardless of the cable environment's noise content. Circuitry may be included for filtering the received test signal based on an understanding of a generic urban noise environment. The apparatus can provide the user with the size and direction of the test signal at a particular testing location.
