An underground cable fault distance locator is a device used to identify and locate faults in underground cables. It helps maintenance personnel quickly find the exact location of faults, reducing downtime and repair costs in power distribution systems, telecommunications, and other infrastructure relying on underground cables.
Signal Injection: The transmitter sends a signal (electrical or acoustic) into the underground cable. When a fault occurs, the signal is reflected or altered at the fault point.
Fault Detection: The receiver detects the altered signal and calculates the distance from the testing point to the fault based on the time it takes for the signal to travel and return.
Distance Measurement: The system provides the operator with the fault’s location, often in meters or feet, allowing for targeted excavation and repairs.
Open Circuits: A break or disconnection in the cable.
Short Circuits: When two conductors within the cable come into contact, causing a direct connection.
Ground Faults: A cable’s conductor comes into contact with the ground, causing unwanted current flow.
Partial Discharges: Low-level electrical faults that do not fully disrupt the circuit but may cause insulation damage over time.
