  • High Voltage Substation Maintenance Upgrades | Nexus

    SF6 gas insulated high voltage circuit breakers. Substation electrical circuit breakers protect the system from faults by providing electrical circuit disconnection and fault-clearing capabilities, and newer gas-insulated SF6 circuit breakers require 2-3x less space than older oil-filled breakers. When installing an SF6 breaker, it’s important to make sure any upgrades integrate well with the existing substation equipment.

  • Electric Power Systems Partnership | Fluorinated Gas

    Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for SF6, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used SF6in circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect SF6 emissions from electric power systems, such as the type and age of the SF6-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of SF6, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of SF6can impact the climate. The electric power industry uses roughly 80 percent of all SF6 produced worldwide. Ideally, none of this gas would b...

  • Introduction to Gas Insulated Substations / Switchgears (GIS)

    As the dielectric strength of SF6 gas is higher than air, the clearances required are smaller. Hence the overall size of each equipment and the complete sub-station is reduced. The various modules are factory assembled and are filled with SF6 gas. Thereafter, they are taken to site for final assembly.
