To radically increase the share of renewables in the energy system, reliable power transmission grids with more capacity and wider reach are needed. At SCiBreak we develop a key technology for such grids, high-voltage fast-acting circuit breaker.

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 …

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.
