In addition to the cost to repair SF 6 leaks, vendor A equipment requires a biennial application of silicon grease to the flange joint and replacement of the flange O-ring seal after 10 years of service to maintain the design leak rate of 1%. At two newly installed GIS, using equipment installed and manufactured by vendor A, most of the flanges were found to be leaking SF 6 in excess of PGE's specification during the commissioning of the equipment.

  • gaz sf6 Monitoring System for GIS – GE Grid Solutions

    SF 6 Monitoring System for GIS. With worldwide scrutiny on SF 6 gas usage, increased environmental reporting requirements and even possible penalties, precise early detection of small gas leaks in Gas Insulated Substations that use so much SF 6 is essential. The B Watch uses the latest generation of EMC resistant digital gas sensors to continuously measure gas pressure and temperatures in order to track changes in density and detect gas leaks down to 0.1% per year.

    To overcome this constraint, a parallel technology was developed, the Gas-Insulated Substation (GIS), using a gas, for example sulphur hexafluoride (SF 6), at high pressure. SF 6 has excellent dielectric properties and is used as the insulating medium between the phases and between the phases and earth. As a consequence, a GIS is much more compact.

  • Three abnormal situations leading to an uncontrolled release

    Abnormal leakage. The method of risk assessment is similar to that used in section “leakage from sf 6 – filled equipment” which deals with normal leakage. Internal fault. An internal fault can develop when an arc is formed abnormally between the main conductors of an item of switchgear, or between a main conductor and an earthed conducting part. External fire. Fires in outdoor installations rarely cause problems because of the relative absence of flammable material in the vicinity of the switchgear.

  • Three abnormal situations leading to an uncontrolled release

    In the case of abnormal leakage of sf6 gas in a medium voltage indoor substation (see figure 2 ), the SOF 2 related to complete escape of Sulfr hexafluoride from one CB would reach 17,5 ppmv. The concentration of SOF 2 in the switchroom at 20% relative pressure loss (commonly the alarm level) would be 3.5 ppmv.
