DESCRIPTION:Electrical utility infrastructure has historically been respons
 ible for less than 10% of reported wildfires in California. However\, fire
 s attributed to power lines account for roughly half of the most destructi
 ve wildfires in the state’s history. Rapid detection of electrical fault
 s and de-energization of the affected power line can therefore play an imp
 ortant role in reducing the potential for utility-related wildfire ignitio
 n.\n\nPower semiconductors offer an opportunity to significantly reduce pr
 otection response times\, potentially to well below one cycle. One approac
 h uses thyristor-based solid-state crowbars to rapidly short-circuit the l
 ine during a fault\, providing a fast-acting protective response ahead of 
 conventional electromechanical switching devices. This additional layer of
  protection can be integrated with existing infrastructure while retaining
  conventional circuit-interruption equipment. Because the crowbar operates
  only during fault conditions rather than continuously conducting load cur
 rent\, it can provide high-speed protection without introducing continuous
  operating losses.\n\nThis presentation will explore the potential applica
 tion of solid-state crowbar protection as a wildfire risk-mitigation techn
 ology\, including its fundamental operating principles\, key technical des
 ign considerations\, integration with conventional protection equipment\, 
 and the modular architecture that allows the concept to scale from low-vol
 tage to medium-voltage distribution systems.\n\nSpeaker(s): Dr. Martin Sch
