• Using a Virtual Main to Mitigate Your Arc Flash Hazard

  Using a Virtual Main to Mitigate Your Arc Flash Hazard What Is an Arc Flash? In electrical power systems, unwanted electrical discharge between conductors results in what is called an “arc flash”—the rapid release of energy in the air. These arc flashes release heat that is 35,000°F, creating a major risk of injury for those […]
