  • Why break the insulating glass unit for gas analysis if

    Mar 23, 2017The fact that small molecule gas is prone to leakage is a challenge, and thus manufacturers aim to ensure the maximum possible content of argon after the gas filling – typically 95% and over. One example is the European standard EN-1279. After 10-year period, the insulating glass unit has to still contain certain percentage of the insulating gas.

  • Transformer Oil Analysis - Kremesti

    Dissolved Gas Analysis is widely accepted as the most reliable tool for the earliest detection of incipient faults in transformers and tap selector units. Hydrocarbon (mineral-based) oils and silicones are used as insulation fluids in transformers because of their high dielectric strength, heat transfer properties and chemical stability.
