The dielectric strength of transformer oil in atmosphere typically ranges from 20 to 30 kV/mm, depending on the specific formulation and condition of the oil. It is essential to regularly test transformer oil using devices such as Globecore’s oil dielectric strength tester to ensure it meets the necessary safety standards and performance requirements, as the dielectric strength can be influenced by factors like contamination, moisture, and degradation over time. Consistent monitoring helps maintain the reliability and efficiency of transformers in industrial applications.
