The method of short circuit fault identification and location in high-voltage transmission line

2013 Sixth International Conference on Advanced Computational Intelligence (ICACI), 2013
That the phenomena of transmission line fault takes place occasionally in our country has a severe impact on power system stability. It has great significance for reliable power supply to identify short circuit fault and cut it quickly. A new method of fault identification and location is proposed in the paper.

Method of Short-Circuit Fault Diagnosis in Transmission Line Based on Deep Learning

International Journal of Pattern Recognition and Artificial Intelligence, 2022
It is important to locate the fault distance and identify the fault types quickly, take effective measures to maintain line stability, and minimize the losses timely when there are short-circuit faults in transmission lines. For this purpose, a method based on deep learning is proposed for short-circuit faults identification in the transmission line ...

A short-circuit transmission line method for PIM evaluation of metallic materials

2006 Asia-Pacific Microwave Conference, 2006
A short-circuit transmission line method for PIM evaluation of metallic materials is proposed in this paper. This method has no restriction of impedance matching at all, and is advantageously free from the low noise termination problem. This enables to treat arbitrarily-shaped samples as a point PIM source, and evaluate them in appropriate current ...
