 This loading guide is based on Arrhenius’ law.
The temperature within a transformer winding varies. Certain areas in a winding are exposed
to higher temperatures than others. The material deterioration rate is highest in high
temperature areas. These areas will reach the end-point first and determine the service
reliability of the whole transformer.
 
The relation between the hot-spot temperature and the average temperature in the windings
may vary from one design to another. The formulas for the hot-spot temperature are general
and may imply an uncertainty that makes the prediction of lifetime consumption
correspondingly uncertain. Manufacturers may be able to provide more precise information on
hot-spot temperatures for their particular design.
When assessing the load capability of a transformer, the ambient temperature as a function of
the load must be taken into consideration.
