Automated distribution fault locating system
IEEE Transactions on Industry Applications, 1996An automated fault locating system was designed and implemented for the Colorado River Agency (CRA) 12.5/7.2 kV distribution system. This automated fault locating system (FLS) was integrated into the Supervisory Control and Data Acquisition (SCADA) system which was installed at a hydro power plant.

Electronics and Power, 1966
Cable faults will always be with us, and the present excavation costs and traffic congestion render it more important than ever to minimise the work done in finding and clearing the troubles. In the future, it seems probable that pulse-reflection tests with an oscilloscope will become of increasing importance for fault location, but the present methods

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 ...

Intermittent Fault Location in Distribution Feeders
IEEE Transactions on Power Delivery, 2012Due to the utilization of fundamental frequency, current impedance-based fault-location methods are able to locate only permanent and linear faults. The duration of the arc in low- and medium-voltage systems can be as short as a quarter of a cycle. This period, which is normal for intermittent faults, is insufficient for fundamental frequency-based ...

On the generation of small dictionaries for fault location
1992 IEEE/ACM International Conference on Computer-Aided Design, 1992Fault location based on a fault dictionary is considered. To justify the use of a precomputed dictionary in terms of computation time, the computational effort invested in computing a dictionary is first analyzed. The number of circuit diagnoses that need to be performed dynamically, without the use of precomputed knowledge, before the overall effort ...

Locating faults before the breaker opens — Adaptive autoreclosing based on the location of the fault
2018 71st Annual Conference for Protective Relay Engineers (CPRE), 2018This paper reviews technical, safety, and economical merits of adaptive autoreclosing based on fault location calculated in real time. These applications include preventing reclosing for faults on cable sections of hybrid lines comprising overhead and cable sections, faults located close to large generating stations, faults on line sections crossing ...

Locating Faults in Photovoltaic Systems Data
2017Faults of photovoltaic systems often result in an energy drop and therefore decrease the efficiency of the system. Detecting and analyzing faults is thus an important problem in the analysis of photovoltaic systems data. We consider the problem of estimating the starting time and end time of a fault, i.e. we want to locate the fault in time series data.

Location of checkpoints in fault-tolerant software
Proceedings of the 5th Jerusalem Conference on Information Technology, 1990. 'Next Decade in Information Technology', 2002Information reduction throughout a program is studied, identifying its impact on the effectiveness of checkpoints. The discussion covers failure masking, function classes that reduce information, the impact of information reduction on failure dependence, information reduction for binary values, and location of checkpoints.

Locating Bridging Faults in Memory Arrays
1991, Proceedings. International Test Conference, 2005A memory array is considered a collection of RAM chips interconnected via data lines, row-select lines and wordselect lines. The stuck-at and bridging fault models are assumed for those lines. For each type of line an algorithm to locate the fault, in the presence of possible faults in thle other lines and possible faults in the RAM chips, is presented.
