AMSC, a Devens technology company that makes systems and products that help control wind turbines and power grids, has teamed up with cable supplier Nexans to unveil a new product for the North American market that is designed to make power grids more resilient, the two companies said in a Wednesday press release.

The product is called a medium voltage superconductor fault current limiter, or SFCL. Destructive fault currents can be caused by such factors as lightning strikes and downed power lines. The new SFCL aims to limit currents to safe, manageable values.
