The Vaisala DGA OPT100 offers exceptional performance for monitoring all fault gases in a transformer. Specifically designed to be maintenance-free and avoid false alarms, it offers the best measurement trends with high long-term stability. It also provides on-line humidity and temperature measurement, as well as a specific system for leak detection (TGP). <\/p>\n

Differential characteristics:<\/b><\/h5>\n
    \n
  • <\/span>Maintenance-free:<\/b> The OPT100 is explicitly designed without gas bottles, filters or mechanical parts, to require no maintenance. No consumables, service, or parts to replace during its lifetime. None of its components have any friction or wear parts and Vaisala’s patented NDIR sensor technology requires no intervention, nor is it affected by temperature or vibration. In addition, the automatic self-calibration system eliminates the effects of oil aging. As the oil ages, volatile compounds are formed that can cause interference with fault gases. Autocalibration detects and eliminates their effects, ensuring that dissolved gas analysis (DGA) results are always reliable.<\/span>\n

    In summary, the OPT100 offers continuous and real field monitoring at no additional cost to the purchase, resulting in a total cost of ownership, reduced to its initial purchase cost.<\/p>\n<\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div><\/div>

      \n
    • Intuitive and easy to install:<\/b> Designed to install in less than two hours. No need for manufacturer-certified technicians to install and program the device, and no need to revisit the device several days later for further programming. After installation, the web-based user interface guides you step-by-step through a simplified, semi-automatic procedure. Even so, ALAVA INGENEIROS offers installation service and training, as well as subsequent remote or on-site assistance. <\/span> <\/li>\n
    • Robust and intelligent design:<\/b> Stainless steel piping, IP66 temperature controlled housing, magnetic pump and valves with no rubbing\/wearing parts, hermetically sealed IR measuring unit to avoid contamination of its optics, no cooling fans required and can work in an operating temperature range between -50\u00b0C and +55\u00b0C. All these features provide excellent performance and durability without the need for maintenance or spare parts of any kind. <\/b> <\/span><\/li>\n
    • Gas extraction in the sample:<\/b> Once the oil sample has been taken, the OPT100 model is the only DGA on the market that performs a vacuum extraction of the gases contained in the sample, just as it is done in the laboratory, not being satisfied only with the gases extracted from the upper part of the sample tank. This guarantees the reliability of the sample taken, extracting up to 95% of the gases contained in the sample. <\/span><\/li>\n
    • Simple communication interface:<\/b> The Vaisala OPT100 has a web server-based interface that completely eliminates the need for additional software. After installation, it is ready for operation and in the event of a disturbance such as a power outage, self-diagnostics allows the equipment to self-adjust and continue monitoring after power is restored. <\/span><\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div><\/div><\/p>\n","protected":false},"excerpt":{"rendered":"
