  • Iso Transformer -- Osborne Transformer

    Osborne’s iso transformer designs are used to step-up, step-down and isolate voltages. Isolation may be used to help provide a degree of secondary-side immunity from voltage spikes and noise (both common-mode and transverse-mode) present on the primary-side system. The isolation can allow separate grounds on both the input and output sides of the transformer.

    Jan 31, 2018 · Though particle counting is reported as an actual count of the number of particles (of a given size, per ml of fluid), most specifications and limits simply refer to ISO codes. The ISO codes, according to the ISO 4406:1999 standard, relate to only three different ranges of particles, ≥4 µm/≥6 µm/≥14 µm. It should be noted that each range is equal to or greater than its designated micron rating, meaning that all particles counted in the ≥14 micron range will be included in the

  • Dissolved gas analysis - Wikipedia

    Dissolved gas analysis is an examination of electrical transformer oil contaminants. Insulating materials within electrical equipment liberate gases as they slowly break down over time. The composition and distribution of these dissolved gases are indicators of the effects of deterioration, such as pyrolysis or partial discharge, and the rate of gas generation indicates the severity. DGA is beneficial to a preventive maintenance program. The collection and analysis of gases in an oil-insulated t
