LimBreak-Rail: New EUREKA-project together with Arcteq Oy on ultra-fast fault detection in railway applications
A bidirectional, ultra-fast DC-breaker, such as the breaker technology offered by SCiBreak, can with great benefits be used also in AC-systems. Especially in 16.7 Hz railway applications, the ability to dramatically reduce the total fault clearance time brings a unique and valuable tool to the grid owners. The requirements on and possibilities enabled by a …
SCiBreak’s DCCB module tested at KEMA
During last week, SCiBreak AB tested a DC circuit breaker module prototype at the KEMA laboratories of DNV GL, as a task within the EU-project PROMOTioN. A fault current of 10.8 kA was delivered by short circuit generators and was interrupted against a transient voltage exceeding 40 kV. These tests verify the function of the …
Concept proved for 10 kA and 40 kV
SCiBreak got some good news for Christmas, a significant milestone was reached. For the first time, a 10 kA current was interrupted against a recovery voltage of 40 kV with SCiBreak’s technology. After ramping up the ratings of the prototype during the whole year of 2017, we thus reached our initial target. The current was …
About Us
SCiBreak is a Swedish company founded in 2014 to commercialize new technology for interrupting electric current. Our technology allows for interruption of high AC or DC currents with high returning voltage within a few milliseconds. Conventional AC breakers need several tens of milliseconds to break and existing DC breakers for high voltage are generally very costly. The parts cost of breakers based on the concept is considerably lower than that of competing solutions.
Our roots are in many ways at KTH Royal Institute of Technology in Stockholm where many of us have worked and studied.
SCiBreak is collaborating with InnoEnergy and Svenska Kraftnät.
