From the National Concrete Masonry Association and Sandia National Laboratories … High-power electrical discharges can trigger explosions reaching upward of 35,000°C, vaporizing steel and spewing hot metal particles. In a power plant, such high-energy arc faults can quickly spread, a condition researchers at Sandia National Laboratories, Albuquerque, N.M., are trying to prevent by finding a new way to peer into flames approximating lightning strike heat. Those flames bear useful information that can help keep power plants operating safely, researchers suggest.
