odm sf6 o2 Leakmate for transformers

Additionally, O2 occurs as a result of the aging and degradation of paper insulation. If the transformer is of relatively recent manufacture (6-10 yrs.) your oil may contain an O2 inhibitor which in effect "absorbs" oxygen and keeps the numbers relatively low. As the inhibitor saturates the O2 numbers will elevate.

  • 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.

  • Field drying of transformer insulation | TD Guardian

    A transformer’s life is determined by the health of the insulation system. If one tiny piece of the insulation in a critical location fails, electrically or mechanically, the transformer is potentially doomed. The estimated life of a transformer is calculated to be approx. 20.5 years (per IEEE C.57.91) minimum when operated as follows:

    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.
