A line signal generator is connected to a metal armour layer of the cable to apply a line signal to the armour. Changes in the line signal current are monitored to detect the condition of the cable. Moisture penetration can be monitored throughout the length of the cable. The armour layer is maintained at a negative potential with respective ground. This provides an additional cathodic protection to the cable.
