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.
For example, lighting up a fault indicator in situations if human intervention is not required induces breakage by causing maintenance personnel to perform work when nothing is already broken. Another example is that enabling fault reporting for Internet network packet delivery failure increases network loading when the network is already busy ...
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 ...
For example, spread-spectrum time-domain reflectometry (SSTDR) is used to detect intermittent faults in complex and high-noise systems such as aircraft wiring. [7] Coherent optical time domain reflectometry (COTDR) is another variant, used in optical systems, in which the returned signal is mixed with a local oscillator and then filtered to ...
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or current flowing to another powered conductor.
In Kosovo, a state-owned energy company plans to destroy a village to make way for expanded coal mining as the government and the World Bank plan for a proposed coal-burning power plant. The government has already forced roughly 1,000 residents from their homes. Many former residents claim officials violated World Bank policy requiring borrowers to restore their living conditions at equal or ...
(For example, a printer that "was working when it was plugged in over there"). However, there is a well known principle that correlation does not imply causality . (For example, the failure of a device shortly after it has been plugged into a different outlet doesn't necessarily mean that the events were related.
