In electric utility service areas with extreme ambient temperatures, strong solar irradiation, and high electric loads, hot-spot temperatures in transformer windings often exceed the recommended 110° Celsius limit. Exceeding this limit can considerably reduce the insulation life of distribution transformers. Specifically, every 8° Celsius increase in temperature beyond the limit yields a doubling of the rate at which the insulation deteriorates, or a halving of the transformer life expectancy. Therefore, it is critical to include all of the heat sources when calculating the transformer hot-spot temperature and the associated loss-of-life. 0.501kg, 0.100/0.100/0.100.
