Multiple issues unreferenced December 2009 notability December 2011 In document ISO CD 10303 226 , a fault is defined as an abnormal condition or defect at the component, equipment, or sub system level which may lead to a failure . According to the Federal Standard 1037C of the United States, the term fault has the following meanings An accidental condition that causes a functional unit to fail to perform its required function. A defect that causes a reproducible or catastrophic malfunction. A malfunction is considered reproducible if it occurs consistently under the same circumstances. In Electric power power systems, an unintentional short circuit , or partial short circuit, between energized conductor material conductor s or between an energized conductor and ground electricity ground . A distinction can be made between Symmetric fault symmetric and asymmetric fault s. Failures in hardware can be caused by random fault s or systematic fault s, but failures in software are always systematic.

Multiple issues unreferenced December 2009 orphan December 2009 notability December 2011 context October 2009 wikify January 2012 A random fault is a Fault technology fault that occurs as a result of wear or other deterioration. Whereas the time of a particular occurrence of such a fault cannot be determined, the rate at which such faults occur within the equipment population on average can be predicted with accuracy. Manufacturers will often accept random faults as a risk if the chances are virtually negligible. A fault can happen in virtually any object or appliance, Most common with electronics and machinery. For example,an Xbox 360 console will deteriorate over time due to dust built up in the fans, this will cause the Xbox to overheat and cause an http support.xbox.com en GB xbox 360 flashing lights two flashinglights error and shut the Xbox down.

Fault coverage refers to the percentage of some type of faulttechnologyfault that can be detected during the test of any engineered system. High fault coverage is particularly valuable during manufacturing test, and techniques such as Design For Test DFT and automatic test pattern generation are used to increase it. In electronics for example, stuck at fault coverage is measured by sticking each pin of the hardware model at logic 0 and logic 1 , respectively, and running the test vectors. If at least one of the outputs differs from what is to be expected, the fault is said to be detected. Conceptually, the total number of simulation runs is twice the number of pins since each pin is stuck in one of two ways, and both faults should be detected . However, there are many optimizations that can reduce the needed computation. In particular, often many non interacting faults can be simulated in one run, and each simulation can be terminated as soon as a fault is detected. A fault coverage test passes when at least a specified percentage of all possible faults can be detected. If it does not pass, at least three options are possible. First, the designer can augment or otherwise improve the vector set, perhaps by using a more effective automatic test pattern generation tool. Second, the circuit may be re defined for better fault detectibility improved controllability and observability . Third, the designer may simply accept the lower coverage.

wikify date April 2011 An intermittent fault , often called simply an intermittent , is a malfunction of a device or system that occurs at intervals, usually irregular, in a device or system that functions normally at other times. Intermittent faults are common to all branches of technology , including computer software .

The rocks on the SW side of the fault have been lifted up forming steep cliffs of Triassic Wingate Sandstone Wingate sandstone and Chinle formation . At the north end of the Moab valley, there is a fault transfer zone, where the fault steps east. This zone transfers the displacement along the fault from one segment to another. Within this zone there is very dense faulting. This is revealed in the road cutting for U.S. Route 191 Highway 191 as seen in this picture taken from the nearby Arches National Park visitor centre.

A fault indicator is a device which provides visual or remote indication of a Fault power engineering fault on the electric power system. Also called a faulted circuit indicator FCI , the device is used in electric power distribution networks as a means of automatically detecting and identifying Fault power engineering faults to reduce outage time. Overhead indicators are used to visualize the occurrence of an electrical fault on an overhead electrical system. Underground indicators locate faults on an underground system. Often these devices are located in an underground vault. Some fault indicators communicate back to a central location using radio or cellular signals. Basic principles During an electrical fault on a grounded system, additional current flows through a conductor, which is picked up by the fault indicator causing a state change on the mechanical target flag, LED , or remote indication device. Ground fault indicators for ungrounded systems sense the vector sum of the current and look for an imbalance indicating a fault on one or more of the three phases.
