New IEEE Standard – Active. Reaffirmed 2008. Recommendations are made, where possible, regarding the performance and evaluation of temperature rise tests on oil-immersed power transformers beyond nameplate ratings. The intent is to assist power transformer manufacturers, and the ultimate users, in evaluating thermal performance of the transformers under varying loads.<\/p>\n
