Abstract :
The tube aging test of oil-filled transfonner electrical insulation system was conducted in closed nitrogen gas atmosphere. Furthermore, another tube aging test was conducted under the condition of flowing air and its results were compared with those of the accelerated aging test of the distribution transfonner in which air was sealed.
