  • SF6 Gas-Insulated Transformer | Transformer | MEIDENSHA

    SF6 gas known for its non-flammabilit and coordinative ability with environmental conditions. Lt was widely used in underground substations and inddor substations at underground shopping areas, traffic systems, and public structures. SF6 Gas-Insulated transfomers are designed to reduce fire hazards and less risk on the environment. By directly coupling with gas-insulated Switchgear, substation space can be minimized as the result of compact facilities.

  • SF6 Insulated Current Transformers – Trench Group

    SF 6 insulated current transformer are used to convert high transmission line currents (up to 6000 A) to standardized low and easily measurable values, which will be used for metering, protection and control of the high voltage system. As such, the need for accurate and reliable current transformation is essential. The reliability and security of Trench gas-insulated instrument transformers is based on over 50 years of innovation with gas-insulated units operating under a wide range of

    Also, SF 6 in the oil can complicate the Dissolved Gas Analysis (DGA) processes that are so important to transformer health assessment and maintenance decisions. For example, dissolved SF 6 will cause some DGA monitors and portable analysers that use IR measurement methods (e.g. Photo Acoustic Spectroscopy, Non-Dispersive IR) to report false high readings for one or more key fault gases.
