The viscosity of Midel transformer oil, such as Midel 7131, is typically around 30-35 cSt (centistokes) at 40°C, which is slightly higher than mineral oil. This viscosity is designed to offer good flow characteristics for effective cooling and insulation in transformer applications.

Condensate polishing ensures high-purity water by removing dissolved ions, suspended solids, and organic contaminants through a combination of mechanical filtration and ion exchange. The ion exchange resins in the system capture cations and anions, effectively reducing the conductivity of the water, while mechanical filters remove particulate matter. Mixed-bed resin units can be used for final polishing to achieve ultra-pure water quality. This process is essential in applications such as power generation, where high-purity water is needed to prevent scaling, corrosion, and equipment damage, thereby improving system reliability and efficiency.

Fuel oil polishing for standby generators is critical to ensure that the fuel remains clean and ready for use during power outages. Fuel stored for long periods can degrade, accumulating water, sludge, and particulates. A polishing system continuously or periodically filters the fuel, removing contaminants and ensuring that the generator operates efficiently and reliably when needed.

Oil quality in x-ray tubes is monitored through regular testing of key parameters such as dielectric strength, moisture content, acidity, and the presence of contaminants like particles and dissolved gases. These tests help identify changes in the oil that could affect its insulating and cooling performance. By regularly monitoring oil quality, potential issues can be addressed before they lead to equipment failure. GlobeCore offers oil filtration systems that help maintain oil quality, removing contaminants and ensuring the oil remains within optimal operating standards for x-ray tubes.

A silicone oil purification system operates by:

Heating the Oil: Reduces viscosity for better purification efficiency.
Vacuum Dehydration: Removes moisture and dissolved gases under vacuum conditions.
Filtration: Passes the oil through multi-stage filters to eliminate particulate contaminants.
Degassing: Extracts air and volatile gases that affect dielectric properties.
Adsorption Treatment: Uses adsorbent materials to remove acids and polar compounds.
Cooling: Returns the purified oil to appropriate temperatures before reintroducing it to the transformer.
This process restores the oil’s insulating and cooling properties, ensuring optimal transformer operation.

A transformer oil purification system removes contaminants like moisture, gases, and particulate matter from the oil. The process typically involves heating the oil to reduce viscosity, passing it through filters to remove solids, and subjecting it to vacuum treatment to extract dissolved gases and moisture. Dehydration and degassing occur under reduced pressure, where water and gases vaporize at lower temperatures. Some systems use adsorption materials to capture acids and oxidation products. Purified oil regains its dielectric strength and cooling efficiency, improving transformer performance.

Cable oil filtration removes solid particles and impurities from the oil, enhancing its insulating and cooling capabilities. Clean oil reduces the risk of electrical discharge and overheating, which can damage the cable’s insulation and conductors. By maintaining oil purity, filtration helps ensure consistent electrical performance, reduces energy losses, and minimizes the likelihood of cable failures, thereby improving the overall efficiency of the power transmission system.

A data set of test scores is being transformed using various methods depending on the specific requirements of oil testing and diagnostics. In the context of industrial oils, transformation can involve calibrating the results from Globecore testers, which measure parameters such as viscosity, acidity, and contaminant levels. This often includes data normalization, applying formulas to correlate raw readings to industry standards, and generating meaningful insights that can guide maintenance or replacement decisions. Each test conducted with Globecore devices provides critical information that can also be aggregated and analyzed over time to observe trends, ensuring that the quality and reliability of industrial oils are maintained effectively.
