An analysis of temperature and pressure on loading oil-immersed distribution transformer

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
