AREVA's Transmission and Distribution (T&D) division and Bruker Energy & Supercon Technologies (BEST) have successfully designed, built and tested a single module of a 13 MVA (2000 A, 6.4 kV) single-phase, shielded-type inductive superconducting fault current limiter (SFCL) at the AREVA T&D Technology Centre in Stafford, UK. The design utilizes a proprietary cryogenic module incorporating BEST's 2nd generation high-temperature superconductors.

Increasing demand for electricity and the restructuring of the power transmission system resulting from deregulation and the increased level of distributed and renewable energy generation can lead to fault current levels above the capability of existing switchgear. A viable solution is to install a current-limiting device that is self-triggering, rapidly-activated within a few milliseconds and fail-safe.

As a result of the tests in Stafford, the following conclusions were drawn:

* The SFCL module limited a prospective 68.5 kApeak fault to 9 kApeak in five milliseconds (¼ cycle)

* Fault current after five cycles (before circuit breaker opening) was reduced by a factor of 10

* The SFCL exhibits fast recovery after a short circuit fault (less than 200 milliseconds) and is expected to withstand a large number of limitation sequences

Commenting on the successful collaboration with BEST on these tests, Gerhard Seyrling, Innovation & Performance Improvement Senior Vice President of AREVA T&D, said, "This product addresses issues with high fault currents that our customers are very concerned with in their networks. We intend to work with BEST to create an industrialized product which will make our customers' grids smarter and further enable integration of distributed generation. This breakthrough technology is set to play an increasingly important role in the future development of smart grids."

"Based on these excellent test results, the feasibility of operation for our shielded, inductive SFCL has been demonstrated, paving the way for future commercialization," said Dr. Burkhard Prause, President and CEO of BEST. "The SFCL certainly meets the expectations for reliability and durability of the most demanding utilities, while at the same time it is a true 'smart grid' device with its ability to rapidly react and recover independent of outside control or triggering."
