Abstract: Disclosed herein are methods, systems, and devices for detecting and locating fluid leaks along a resistance cable. According to one embodiment, a system for monitoring a sense cable that comprises a source wire and a resistance wire is disclosed. The system includes control circuitry and current measurement circuitry coupled with the control circuitry. The control circuitry is configured for determining a first current value of a first measured leak current at a near end of the resistance wire and determining a second current value of a second measured leak current at a far end of the resistance wire. The control circuitry is further configured for determining an approximate location of a leak coupling via a fluid between the source wire and the resistance wire based on the first current value, the second current value, and a resistance parameter of the resistance wire.
