transformer temperature rise explained
Page 1 of 2 TEMPERATURE RISE General An isolation transformerâs main purpose is to transfer electrical energy from the primary coil to the secondary coil (input to output).In doing this, the transformer converts some of the electrical energy into heat energy. Transformers develop heat in the same manner as lightbulbs. desirable indoor dry type transformer is convection (self) cooled and has a maximum temperature rise of 115Â° C with an insulation temperature of 200Â° C. Beware of the 80Â° C rise transformers. They are often a 115Â° C rise transformer that has approach.
