Bruker Energy & Supercon Technologies (BEST) and Schneider
Electric Sachsenwerk GmbH have announced the successful
completion of another step in the development of a shielded,
inductive superconducting fault current limiter (iSFCL), which
is to begin field test operations in the Stadtwerke Augsburg
(Germany) grid in 2013.
Testing of a subscale device under expected operating
conditions was performed at the Institute for High-Voltage
Engineering and Electrical Energy Systems of the University of
Braunschweig, a leading German research institute in the field of
high voltage and power systems engineering.
This device implements the concept to be used in the full-size
iSFCL system and utilises BEST’s 40mm-wide second generation
(2G) high temperature superconductors (HTS), specifically
designed for application in fault current limiters.
During the tests in Braunschweig, the device functioned as
predicted in more than 100 triggered short-circuits.
Due to the novel design of the superconducting modules, the
system withstood fault durations of up to 500 milliseconds,
believed to be the longest withstand time reported worldwide
with HTS coated conductors.
The results validated the performance parameters predicted
by computer models, thus enabling extrapolation to other grid
topologies and requirements.

CTC contract for HVDC project
CTC Marine Projects, part of DeepOcean Group Holding AS,
has been awarded a contract for Dolwin 1, a high-voltage
cabling project off the German coast to link offshore wind
projects to the grid. The contract for EMAS AMC, will include
the trenching of 62.34km of bundled HVDC power cable
from a 14m water depth and trenching of a power cable.
