  • Transformer Insulation and Temperature Rise

    Temperature Rise refers to the average rise in temperature in the transformer coils at full load. The expected temperature rise is a function of the current and impedance (efficiency) of the transformer. Standard rise temperatures are 150°C, 115°C, 80°C, and 50°C. These ratings have traditionally been paired with insulation classes as follows:
