Big fizzing electrical arcs are fun, and handled properly, not too dangerous either. The Jacob’s Ladder is one such piece of arc-generating equipment, one that featured heavily in vintage sci-fi films ...

The study of vacuum arc behaviour and interrupter technologies represents a cornerstone in advancing the safety and efficiency of high-voltage electrical systems. Vacuum arcs are plasma discharges ...

The U.S. high-voltage grid must evolve to accommodate dynamic, bidirectional flows from an increasing number of DERs and ...

Particle simulations reveal more raindrops, packed more tightly together, lead to earlier streamer discharges in high-voltage DC transmission lines.
