  • Sulfur Hexafluoride-Filled Extrinsic Fabry–PÉrot

    CONCLUSIONA compact diaphragm-based EPPI fiber-optic sensor for in situ PD monitoring in high voltage power transformers has been developed. Because of the use of the side-hole single-mode fiber, which works as both a waveguide and a gas channel, electric negative gas is able to be filled into the FP cavity after the fabrication of the sensor to increase its resistance to the high electric stress in transformers.

  • SF6 Transmitter - draeger.com

    When insulating switchgear or transformers, sulfur hexafluoride (SF6) is used. Since it is technically almost impossible to hermetically seal these systems, emissions can escape into the environment. Gas detection systems from Dr ger make it possible to detect even the smallest leaks at an early stage and initiate corrective measures.
