- The hot spot factor enables the determination of the hot spot temperature from temperature rise tests. This paper is significant because it interprets the hot spot factor as the maximum dimensionless temperature for the first time based on dimensional analysis. This physical interpretation replaces the empirical interpretation in the transformer industry for decades and provides insights on the determination of the hot spot factor. This interpretation/understanding of hotspot factor and the modelling expertise of the first author was employed by national grid (Dongsheng.Guo@nationalgrid.com; gordon.wilson@uk.ngrid.com) to verify the thermal design of a potential transformer provider from China.
