Open Transistors Fault-Tolerant Schemes of three-Phase Dual Active Bridge DC-DC Converters
(Institute of Electrical and Electronics Engineers, 2021-03)
This work proposes fault-tolerant schemes for open-transistor faults applied to three-phase dual active bridge converters (TPDABC), using different transformers: star-star, delta-delta, and delta-star. The proposal consists ...
Distribution systems fault analysis considering fault resistance estimation
(ELSEVIER SCI LTD, 2011)
Fault resistance is a critical component of electric power systems operation due to its stochastic nature. If not considered, this parameter may interfere in fault analysis studies. This paper presents an iterative fault ...
Fault Tolerant Reconfiguration System for Asymmetric Multilevel Converters Using Bi-Directional Power Switches
(IEEE, 2007)
Asymmetric multilevel converters can optimise the number of levels by using H bridges scaled in power of three. The shortcoming of this topology is that the H bridges are not interchangeable and then, under certain faulty ...
Energization Simulations Of A Half-wavelength Transmission Line When Subject To Three-phase Faults-application To A Field Test Situation

Detection and phase identification of inter-turn short-circuit faults in three-phase induction motors using MEMS accelerometer and Hilbert transform
(2021-08-15)
Three-phase induction motors (TIMs) play a key role in the industrial scenario. Due to their robustness, low cost, and efficiency, TIMs have been increasingly used in industrial applications, making them the main source ...
Improved Fault Location on Distribution Feeders Based on Matching During-Fault Voltage Sags
(Institute of Electrical and Electronics Engineers (IEEE), 2009-04-01)
A fault location algorithm for distribution feeders based on matching during-fault voltage sags is presented. The basic principle of the algorithm is based on the fact that when a fault occurs on the feeder, voltage sags ...
