  2. 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 ...

  3. Failure detector - Wikipedia

    en.wikipedia.org/wiki/Failure_detector

    The construction of a failure detector is an essential, but a very difficult problem that occurred in the development of the fault-tolerant component in a distributed computer system. As a result, the failure detector was invented because of the need for detecting errors in the massive information transaction in distributed computing systems.

  4. Fault indicator - Wikipedia

    en.wikipedia.org/wiki/Fault_indicator

    In electric power distribution networks, a fault indicator is a device which provides visual or remote indication of a fault on the electric power system. Also called a faulted circuit indicator (FCI), [1] the device is used in electric power distribution networks as a means of automatically detecting and identifying faults to reduce outage time.

    A defect detector would sound like this: (This was the read out of CSX train Q452-05 by the Campville Defect Detector on April 6, 2019. The defect detector is located at Campville, Florida, on the CSX Wildwood Subdivision.) CSX EQUIPMENT DEFECT DETECTOR. MILEPOST 7-0-0-POINT-1. NO DEFECTS. NO DEFECTS. TOTAL AXLES 7-3-8. TRAIN LENGTH 1-3-7-6-4 ...

  6. 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.

  7. 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.

  8. Control reconfiguration - Wikipedia

    en.wikipedia.org/wiki/Control_reconfiguration

    In the nominal, i.e. fault-free situation, the lower control loop operates to meet the control goals. The fault-detection (FDI) module monitors the closed-loop system to detect and isolate faults. The fault estimate is passed to the reconfiguration block, which modifies the control loop to reach the control goals in spite of the fault.

  9. Arc-fault circuit interrupter - Wikipedia

    en.wikipedia.org/wiki/Arc-fault_circuit_interrupter

    An arc-fault circuit interrupter (AFCI) or arc-fault detection device (AFDD) [1] is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring. Loose connections, which can develop over time, can sometimes become hot enough to ignite house fires.
