Liquefaction System for extra high Voltages

Liquefaction System for extra high Voltages

Liquefaction has caused significant property damage in many earthquakes around the world, and is a major hazard associated with earthquakes in Utah. The 1934 Hansel Valley and 1962 Cache Valley earthquakes caused liquefaction, and large prehistoric lateral spreads exist at many locations along the Wasatch Front.

  • AC High Voltage Circuit Breakers - IEEE Web Hosting

    2017-10-20AC High-Voltage Circuit Breakers isolate faulted parts of the system. Considering a filling pressure of 7,5 bar (g). at 20&C, liquefaction occurs when temperature reaches -25&C, the residual gas density corresponds to 6.49 bar (g) at 20&C. Partial liquefaction is acceptable for AIS but generally not for GIS.
