  • Study on a new type optic-electric transformer - NASA/ADS

    2006-2-1This paper presents an optic-electronic voltage transformer insulated by SF6, Which is applied in 500KV (line voltage) power system. The voltage sensor is based on converse piezoelectric effect in a quartz crystal. High voltage is exerted on the quartz crystal after being divided by cylinder capacitor divider, piezoelectric deformation is sensed by elliptical-core dual-mode fiber around theCited by: 2

  • Gas density monitors and gas density sensors for SF6 and

    Trafag gas monitoring devices measure the gas density directly, i.e. SF 6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF 6 Gas Density Sensors, or by combining both principles, i.e.SF 6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF 6 gas density.

  • SF6 gas in medium-voltage switchgear | TD Guardian

    SF6 is used extensively worldwide for low switching capacity switches. In these applications, SF6 allows for extremely compact switching devices, sealed-for-life construction, and very low maintenance. Environmental issues In recent years, SF6 has been widely discussed in the environmental arena. SF6 is recognized as a very potent greenhouse gas.

    High voltage transients following equipment switching or balanced and unbalanced faults can involve a rich content of high frequencies. Furthermore, often the nature of the transient’s frequency response can be affected by introduction of passive measuring devices such as inductive or capacitive sensors.
