DC‐presaturated fault current limiter for high voltage direct current transmission systems

open access: yesHigh Voltage, 2021
The authors present a 500 kV real‐dimension DC‐presaturated fault current limiter (PFCL) with a steady‐state rated current of 2 kA for limiting large fault current of 8 kA with high rate of rise. These characteristics of the fault current can be a threat

Translophagy—A potential link between autophagy impairment and translational errors

open access: yesFEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Superconducting Fault Current Limiters for HVDC Systems

open access: yesEnergy Procedia, 2015
AbstractHigh-voltage direct current (HVDC) transmission systems using Voltage-Source Converters (VSC) are widely recognized as offering significant potential for long distance high power delivery, particularly for offshore wind farm connections. One of the barriers for the development of multi-terminal HVDC systems is the lack of technologies which ...

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Study of Superconducting Fault Current Limiter Device in a AC Railway System [PDF]

open access: yesInternational Journal of Railway Research, 2015
Development of the electric networks led to more interconnection in this system, therefore high level of short circuit faults flows in the networks. Many destructive damages such as instability, insulation problems and voltage mitigation can highly play ...

The use of fault current limiter to reduce the operating time of relays [PDF]

open access: yesمجله مدل سازی در مهندسی, 2018
In distribution network with displacement at network level, the fault current does not significantly change and it is not possible to effectively utilize the inverse time over-current relays, since, if the number of primary and backup relays increases ...

Fault Current Limitation Coordination in Electric Power Grid With Superconducting Fault Current Limiters

open access: yesIEEE Transactions on Applied Superconductivity, 2018
This paper proposes the concept of “fault current limitation coordination” in a future electric power grid with multiple superconducting fault current limiters (SFCL). Not only the fault current limitation of each SFCL on a transmission line, but also the transient stability of the grid with SFCLs should be taken into account, because the disturbance ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

open access: yesFEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
