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.
Fault reporting is a maintenance concept that increases operational availability and that reduces operating cost by three mechanisms: Reduce labor-intensive diagnostic evaluation Eliminate diagnostic testing down-time
The passage of the MTJ causes mantle material to flow into the region vacated by the Gorda plate. Once this hot mantle material is south of the triple junction, it cools, stiffens, and accretes to the adjacent lithosphere, eventually welding to it and moving along with it, analogous to the motion of a conveyor belt.

Ideally, a fault management system should be able to correctly identify events and automatically take action, either launching a program or script to take corrective action, or activating notification software that allows a human to take proper intervention (i.e. send e-mail or SMS text to a mobile phone). Some notification systems also have ...
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 ...
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 protection 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 ...
A weak July jobs report just triggered one of the most well-known, and historically accurate, recession indicators: the Sahm Rule.But the rule’s inventor, Claudia Sahm, pushed back against the ...
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.
