Abstract

This paper presents the analysis of temperature and pressure on loading oil-immersed distribution transformer at rated load. The tested transformer is sealed type oil-immersed distribution transformer of 400 kVA 3ph 50 Hz 22000-400/230 V Dyn 11. The results was useful for developing the design, correction, protection, load specification and temperature estimation of transformer with efficiency, in order to improve better cooling and transformer tank´s strengthen. And these will increase transformer aging and stability of distribution system
