Regulators still don't know what caused the flash crash on May 6, but their pilot program of putting circuit breakers on a bunch more stocks goes into full gear this week. Circuit breakers, which ...
High-voltage DC circuit breaker. HVDC circuit breakers are difficult to build because of arcing: under AC the voltage inverts, and in doing so crosses zero volts, dozens of times a second. An AC arc will "self-extinguish" at one of these zero-crossing points, because there cannot be an arc where there is no potential difference.
Schneider Electric SE. Schneider Electric SE is a French multinational company that specializes in digital automation and energy management. [3] [4] It addresses homes, [5] buildings, [6] data centers, [7] infrastructure and industries, [8] by combining energy technologies, real-time automation, software, and services.

Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, SF 6 circuit breakers are widely ...
