Transmission line short circuit analysis by impedance matrix method
International Journal of Electrical and Computer Engineering (IJECE), 2020 Fault analysis is the process of determining the magnitude of fault voltage and current during the occurrence of different types of fault in electrical power system. Transmission line fault analysis is usually done for both symmetrical and unsymmetrical faults.

Development of the method of determining the location of a short circuit in transmission lines
Journal of Physics: Conference Series, 2021 Abstract One of the serious problems of the reliable functioning of energy systems is the disruption of the performance of overhead and cable transmission power lines caused by various reasons. Most of the power outages occur in distribution networks.

A new technique for the transient simulation of transmission lines inclusive of skin effect [PDF]
, 2001 A new approach is presented for the transient simulation of lossy transmission lines in high-speed circuits. The approach is based on developing a model for the transmission line which is structured around natural modes of oscillation unlike other ...

Polynomial Chaos-Based Tolerance Analysis of Microwave Planar Guiding Structures [PDF]
, 2011 This paper focuses on the derivation of an enhanced transmission-line model allowing to describe a realistic microwave interconnect with the inclusion of external uncertainties, like tolerances or process variations. The proposed method, that is based on

International Journal of Electrical Power & Energy Systems, 2016 Abstract In power system, there are partial coupling lines under different voltage level because of the development of power system. When faults occur on these lines, zero-sequence mutual impedances bring difficulty to short-circuit calculation. To solve the problem, a new method is proposed in this paper.
