Fault test analysis in transmission lines throughout interfering synchrophasor signals

open access: yesICT Express, 2019
The distribution of power supplies be obliged to offer reliable, superior-quality in power. To obtain good power quality the transmission line faults identification should be more precise, consistence and complete rectification is required. The faults in

CAUSES OF INDEFINITE FAULTS IN ESTONIAN 110 kV OVERHEAD POWER GRID; pp. 225–243 [PDF]

open access: yesOil Shale, 2013
The study considers causes of indefinite faults in the 110 kV over­head power grid in Estonia. The number of indefinite faults (flashovers on over­head line insulators) has increased significantly in the last years, causing a lot of problems to the ...

Fault classification on transmission line of 10kV rural power grid [PDF]

open access: yesProceedings of the 2015 4th International Conference on Sensors, Measurement and Intelligent Materials, 2016
This paper proposes a technique using Discrete Wavelet Transform (DWT) and Back-Propagation Neural Network (BPNN) to identify the fault types on transmission line of 10kv rural power grid. The PSCAD is used to simulate fault signals. The mother wavelet daubechies4 (db4) is employed to decompose high frequency component from these signals.

A Review of Fault Diagnosing Methods in Power Transmission Systems [PDF]

open access: yesApplied Sciences, 2020
Transient stability is important in power systems. Disturbances like faults need to be segregated to restore transient stability. A comprehensive review of fault diagnosing methods in the power transmission system is presented in this paper. Typically, voltage and current samples are deployed for analysis.
