IEEE Transactions on Instrumentation and Measurement, 2013
We present a method for estimating the bandwidth and the measurement errors of the shorted transmission line method used to obtain the permeability and the permittivity of magnetic materials. The permeability and the permittivity of a toroidal test sample are determined by measuring the reflection coefficients of a shorted coaxial transmission line and

The method of short circuit fault identification and location in high-voltage transmission line
2013 Sixth International Conference on Advanced Computational Intelligence (ICACI), 2013That 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, 2022It 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, 2006A 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 ...
