A Fault Locator For Integrated Optics
Optical Fiber Sensors, 1992Power of resolution of a fault locator has been improving by leaps and bounds. The best values reported so far are of an order of millimeters and the locators are primarily used for finding faults in the bulk media such as breaks in an optical fiber.

1991, Proceedings. International Test Conference, 2005
A two-stage procedure for locating VLSI faults is presented. The approach utilizes dynamic fault dictionaries, test set partitioning, and reduced fault lists to achieve a reduction in size and complexity over classic static fault dictionaries. An industrial implementation is reported in which faults were injected and diagnosed in a VLSI chip and the ...

Locatability of Faults in Combinational Networks
IEEE Transactions on Computers, 1971A formal model for the study of reliable combinational networks is introduced and used to determine network properties conducive to the location of faults. The usual concept of fault location is generalized to be an interval on the partially ordered set of subsets of network nodes that classifies nodes into three disjoint sets: a faulty set, a fault ...

A two stage fault location algorithm for locating faults on transmission lines
2013 International Conference on Computation of Power, Energy, Information and Communication (ICCPEIC), 2013A continuous and reliable electrical energy supply is the objective of any power system operation. Electricity is the driving force behind industry and subsequently economy. There are various types of faults appear in power system. Faults can appear due to bad weather conditions, equipment damage, equipment failure, environment changes and many other ...

Before attempting to locate underground cable faults on direct buried primary cable, it is necessary to know where the cable is located and what route it takes. If the fault is on secondary cable, knowing the exact route is even more critical. Since it is extremely difficult to find a cable fault without knowing where the cable is, it makes sense to ...

Sensor Location for Enhancing Fault Diagnosis
Industrial & Engineering Chemistry Research, 2016Multivariate statistical control techniques have been successfully applied to the detection and isolation of process faults. Because those strategies evaluate the current process state using the measurement values and the normal operation model, their performance is strongly influenced by the sensor network installed in the plant.

Transmission line fault location using digital fault recorders
IEEE Transactions on Power Delivery, 1988A technique for the location of transmission line faults using voltage and current measurements from one end of the faulted line is presented. The method differs from past approaches in that a time domain rather than a frequency domain representation of voltage and current is used.

DG impact on three phase fault location. DG use for fault location purposes?
2005 International Conference on Future Power Systems, 2005In this paper a novel approach for fault location in distribution networks is presented. The distributed generator's (DG) effect in such a network is studied and its influence on a simple fault location method is analyzed. Two DG models are considered - an ideal and a realistic one, for the validation of the fault location algorithm.

Electronics Education, 1991
Our computer department had a problem with its Nimbus network and they approached me with the suggestion that it would be a difficult technical problem to locate a suspected fault in the cable system. I felt instinctively optimistic, recalling the classic physics experiment in which pulses are sent down a cable of measured length and their times of ...

Enhanced distribution feeder fault location
2014 67th Annual Conference for Protective Relay Engineers, 2014Accurate fault location in distribution networks of power systems is an essential technology, yet faces more challenges than that in transmission systems. This paper presents a novel method for feeder fault location using current/voltage sensors sparsely deployed in the network.
