Managing the Bulk Flow: Innovation in the High Voltage Switchgear Market

When electricity travels hundreds of kilometers from a hydroelectric dam in the mountains to a megacity on the coast, it does so at very high voltages—typically 110 kV, 220 kV, or even 800 kV. At these levels, the stresses on equipment are extreme. An arc flash at 400 kV can reach temperatures of 20,000°C, hotter than the surface of the sun. Containing and interrupting such arcs is...
