What are the standard transformer oil tests?

Standard transformer oil tests primarily include the assessment of dielectric strength, moisture content, acidity, interfacial tension, flash point, and pour point. Dielectric strength tests, which are crucial for evaluating the insulating properties, measure the oil’s ability to withstand electrical stress. Moisture content assessments determine the presence of water, which can significantly impact the oil’s performance and longevity. Acidity tests are performed to check for oxidation products that can corrode insulation materials. Interfacial tension tests help in understanding the contamination level of the oil. Additionally, flash point and pour point tests are vital for ensuring the oil’s safety and operational behavior in various temperatures. Globecore offers advanced testers designed specifically for these transformer oil tests, ensuring precise and reliable diagnostics to maintain the quality and performance of industrial oils.
