N2 - This paper introduces a planning tool developed for estimating the maximum time-varying (dynamic) load that a substation distribution transformers can tolerate without violating hottest-spot (HST) and top-oil temperature (TOT) thermal limits. Presented are two kinds of HST and TOT models: the traditional ANSI Clause 7 models and linearized thermal models with coefficients optimized through linear regression to reveal the relationship between HST, TOT, ambient temperature and load. These models, along with Newton's method, are shown to be capable of performing dynamic loading calculations.
