2. Cable fault location - Wikipedia

   en.wikipedia.org/wiki/Cable_fault_location

   The conventionally used aid in cable fault testing and location is the cable test van. The van is installed with conventional cable measuring systems for quickly reaching the location of any cable fault. In 20 years that followed, over 2000 fault location vehicles were manufactured, more than half of which were intended for the former USSR.

3. Cable locator - Wikipedia

   en.wikipedia.org/wiki/Cable_locator

   A cable locator or cable avoidance tool (CAT) is an instrument used for detecting the presence and approximate location of buried services in advance of undertaking excavation works. It aims to avoid accidents while excavating. [ 1 ]

4. Murray loop bridge - Wikipedia

   en.wikipedia.org/wiki/Murray_loop_bridge

   The Murray loop bridge is a bridge circuit used for locating faults in underground or underwater cables. [1] [2] It has been used for more than 100 years [3] but is being replaced by the more precise time-domain reflectometer. One end of the faulted cable is connected through a pair of resistors to the voltage source. Also a null detector is ...

5. Time-domain reflectometer - Wikipedia

   en.wikipedia.org/wiki/Time-domain_reflectometer

   Time-domain reflectometer for cable fault detection. A time-domain reflectometer (TDR) is an electronic instrument used to determine the characteristics of electrical lines by observing reflected pulses.

6. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...

7. Fault detection and isolation - Wikipedia

   en.wikipedia.org/wiki/Fault_detection_and_isolation

   Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
