Fault and splice finding system and method

A method of finding a fault in an electrical cable comprising the steps of:

• introducing a pulsed electrical signal into a near end of an electrical cable including the step of utilizing pulse compression to produce the pulsed electrical signal, the pulsed electrical signal producing second and third pulses of electrical energy representative of the reflected electrical energy from a fault in the cable and reflected electrical energy from a far end of the cable;
• sensing, adjacent the near end of the cable, the pulsed electrical signal and the second and third pulses and providing an indication of a time between the second and third pulses;
• sensing the time between the pulsed electrical signal and the third pulse at a plurality of different positions along the electrical cable until a position is reached at which the time between the pulsed electrical signal and the third pulse is approximately equal to the indication of the time between the second and third pulses;
• noting the position of the fault at the position along the electrical cable where the times are equal.
