  • Electric power distribution - Wikipedia

    Electric power distribution is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 35 kV with the use of transformers. Primary distribution lines carry this medium voltage power to

  • Types of High Voltage Circuit Breaker in Substation

    Jan 25, 2017Sulfur hexafluoride (SF6) gas is an alternative to air as an interrupting medium. SF6 is a colorless nontoxic gas, with good thermal conductivity and density approximately five times that of air. The principle of operation is similar to the air blast breakers, except that the SF6 gas is not discharged into the atmosphere.
