Abstract :
The summary form only given. Primary, secondary, electromagnetic core, and cooling material (oil or SF6 gas) temperature equations are developed and differentially calculated in varying load current and ambient temperature in this paper. The winding hottest-spot temperature shall be integrated simultaneously for 24 hours (one day) to acquire aging loss. Then individual loading guide for power transformers are introduced and proposed as a new method for evaluating transformers of aging loss.
