Fault Location Using Voltage Measurements
IEEE Power Engineering Review, 2001This paper presents a novel method for locating short-circuit faults in electric power systems. The origins of the method are in the concept of vulnerability contours, which is used in assessing the likelihood of voltage sags effecting a given network area. The method is applied in an off-line step and an on-line step.

Inspection Policies for Fault Location
Operations Research, 1984When a system fails it may not be obvious which components are at fault. Locating faulty components to be replaced may require a series of inspections each of which reveals the state (functioning/failed) of one of the components. The order in which components are inspected and replaced can greatly affect the cost to restore the system to an operating ...

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.

IEEE Transactions on Industry Applications, 1973
Results have shown that the most practical approach to locating cable faults consists of a three-step procedure known as the System Approach. By this process various test instruments are employed to first characterize a fault according to its electrical parameters; to next localize the fault to an approximate location by measurements from a terminal ...

Electrical Engineering, 1948
The inspection of circuits by pulse reflection methods is well known to communications engineers. In particular this technique has been used in inspecting high-frequency coaxial telephone and television lines. The “Linascope” is an electronic instrument for locating faults on open-wire telephone and transmission lines. The unit generates repetitively a

Line-fault locator using fault-generated surges
Electrical Engineering, 1948The problem of locating faults on high-voltage transmission lines is an old one, but is becoming more important as distances grow longer and more lines are built through isolated mountain and desert areas.

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

IEEE Transactions on Power Delivery, 1998
This paper describes the use of wavelet transforms for analyzing power system fault transients in order to determine the fault location. Traveling wave theory is utilized in capturing the travel time of the transients along the monitored lines between the fault point and the relay.

Underground Cable Fault Distance Locator
SSRN Electronic Journal, 2021Underground cables undergoes a wide variety of faults due to underground conditions, wear and tear, etc. Diagnosing fault source is difficult and the cable should be fully taken out from the ground to check the faults. The project work is intended to detect the location of fault in underground cable lines from the base station in km using a micro ...

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 ...
