1. Apparatus for localizing faults within a power line, comprising:
- a) an electromagnetic sensor interface for receiving a test signal propagating through said power line and detected by an electromagnetic sensor positioned proximate to said power line;
b) signal conditioning means electrically coupled to said electromagnetic sensor interface for conditioning said received test signal;
c) processing means for processing said received test signal using predetermined test signal signatures to generate usable power line fault detection data; and
d) communicating means responsive to said processing means for communicating said usable power line fault detection data.

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.
