Solid-state design improves on existing fault current
limiters
A local power failure in Ohio ten years ago caused a series
of cascading power failures that resulted in a massive blackout that affected
50 million people and caused billions of dollars in damage and lost revenue.
Such blackouts could be prevented in the future, thanks to a
new piece of equipment developed by engineering researchers at the University
of Arkansas. The device regulates or limits the amount of excess current that
moves through the power grid when a surge occurs.
