An oxidation stability test device compliant with IEC 61125 and ASTM D2440 evaluates the degradation performance of insulating oil through oxidation.
We have designed a device that meets the needs of our customers, featuring a simple and minimal design with a minimal number of components. Due to its characteristics and price, mineral oil is the most commonly used oil in transformers. The drawback is that it undergoes thermal and electrical stress in the atmosphere during operation, leading to oxidation and deterioration of its insulating properties. Over time, acidity increases, resulting in the formation of sludge. Oil aging analysis helps determine the "age" of the oil, which more accurately predicts the timing for oil replacement. This enables efficient use of the oil throughout its entire lifespan and prevents damage to the transformer caused by degraded oil.

basic information
Device Overview The device has a unique design within its class. With an excellent user interface, it will change the way fluid aging is measured. A single module consists of a rigid aluminum frame surrounded by matte-finished polymer sides. There is a dry bath for oil maturation analysis, and it features a configuration for six glass apparatuses. Temperature and airflow are adjusted with extremely high stability and reliability. We employ the dry bath method, keeping the work area clean, avoiding the generation of harmful fumes, and reducing the cleaning time for glassware. The device includes an independent sample holder that can be easily removed for further analysis. The modular design allows for easy mobility and the option to stack multiple modules as needed. A single module can operate as an independent device or connect multiple modules to function as a single device for a large number of samples. Monitoring can be done through a single user interface. Our system provides a low-cost sample analysis solution and facilitates easy upgrades to larger systems.

Applications/Examples of results
The oxidation device for insulating liquid is constructed in accordance with IEC 61125 (formerly IEC 1125) standards and guidelines, ensuring the reliability of measurements. Aging assessments are conducted using standard testing methods (formerly Method C). This testing method relates to both inhibiting and non-inhibiting liquids using oxygen. For advanced users, it is also possible to create custom methods that allow for the setting of start times, block temperatures, and flow rates through oil samples. Each module can simultaneously execute different methods (standard testing methods or custom methods). Applicable tests: Sludge formation Soluble acidity, SA Volatile acidity, VA Total acidity, TA or neutralization value Oxidation rate Dielectric dissipation factor (DDF) or tan delta
