Abstract

Results of temperature rise tests performed in accordance with PC57.119/Draft 12, Recommended Procedures for Performing Temperature Rise Tests on Oil-Immersed Power Transformers at Loads Beyond Nameplate Ratings, are presented. Tested data is compared with calculated values using IEEE and IEC loading guide equations and exponential power constants are determined and are compared with those given in the loading guide. Discussion is offered that may be useful in future drafts of and to the users of the proposed test procedure
