Test insulated wires in multiple-conductor cables.
What does a Cable Tester do?
Tests insulated wires in aerial, underground, or submarine multiple-conductor cables to determine continuity, insulation, and correctness of cable loading, using standard testing procedures and impedance, resistance, and frequency oscillating meters. Listens for sound of escaping insulating gas from hole in cable sheathing to locate defects in cable. Determines continuity, insulation, capacity imbalance, and cable loading, using meters, such as capacity and resistance bridges. Prepares report identifying location and cause of malfunctions. May drive motor vehicle along route of cable, climb poles, and ride in cable car from pole to pole on cable strand to perform tests. May direct CABLE SPLICER in correction of malfunction.
