Influence of the voltage taps position on the self-field DC and AC transport characterization of HTS superconducting tapes

open access: yes, 2013
The current-voltage (I-V) curve is the basic characteristic of a superconducting wire or tape. Measuring I-V curves is generally problematic when samples have poor stabilization.

High-temperature superconducting fault current microlimiters

open access: yes, 2009
High-temperature superconducting microbridges implemented with YBa(2)Cu(3)O(7-delta) thin-films are shown to be possible fault current limiters for microelectronic devices with some elements working at temperatures below the superconducting critical ...

A transient and non-unit-based protection technique for DC grids based on the rate-of-change (R-o-C) of the fault induced travelling wave components [PDF]

open access: yes, 2019
This paper presents a transient and non-unit-based protection scheme for consideration in DC grids of the future. The technique utilises the rate-of-change (R-o-C) of the associated travelling wave components following the occurrence of a fault to ...

Behavior Of Superconducting Fault Current Limiter Under Fault Condition

open access: yes, 2017
Now a days due to increase in electricity demand for the purpose of industrialization, agriculture, domestic and educational etc there exists more chances of fault occurance. The Faults occurs due to insulation damaging, breaking of conductor, short circuit, lightning etc.

Resistive DC fault current limiter

open access: yesThe Journal of Engineering, 2017
The DC fault current of bipolar short‐circuit fault rises rapidly due to the low damping performance of the modular multilevel converter‐high‐voltage DC (MMC‐HVDC) system. It is of great engineering significance to study the DC fault current limiter (FCL) in HVDC systems for suppressing the DC fault current, resulting in making the DC circuit breaker ...
