Abstract: This guide provides recommendations for loading mineral-oil-immersed transformers and step-voltage regulators with insulation systems rated for a 65 °C average winding temperature rise at rated load. This guide applies to transformers manufactured in accordance with IEEE Std C and tested in accordance with IEEE Std C, and step-voltage regulators.

The paper insulation used today in liquid-filled transformers is thermally upgraded, allowing a 65 [degrees] C average winding temperature rise as standard. Until the '60s, 55 [degrees] C rise was the standard. Sometimes, transformer specifications are written for a 55 [degrees]/65 [degrees] C rise.

This guide provides recommendations for loading mineral-oil-immersed transformers and step-voltage regulators with insulation systems rated for a 65?C average winding temperature rise at rated load. This guide applies to transformers manufactured in accordance with IEEE Std C and tested in accordance with IEEE Std C, and step-voltage regulators manufactured and tested in.
