Transformer temperature controller


The winding temperature indicator is a special-purpose instrument using the simulated temperature measurement technique to measure the temperature of the hottest portion of the transformer winding,which is obtained as the summation of T0 and △T , or T=T0+△T,where,T0 is the oil temperature in upper part of the transformer, which can be easily measured; and △T is the temperature rise caused by the rise of the transformer loading current.
