What are the specifications of Petromin transformer oil according to IEC 60296?

The specifications of Petromin transformer oil according to IEC 60296 include parameters such as dielectric strength, viscosity, flash point, and pour point. Specifically, the oil must have a minimum dielectric strength of 30 kV for 2.5 mm gap, a viscosity of 12-70 mm�/s at 40�C, a flash point above 140�C, and a pour point not exceeding -30�C. These specifications ensure the oil’s effectiveness in insulating and cooling power transformers.
