    Abstract

    The use of thermal modelling to increase the permissible load-carrying capability of distribution system transformers is attracting increasing interest. Many reported approaches calculate the rating of transformers in real-time in response to system conditions. In this paper, we describe an experiment to validate and tune the parameters of such a thermal model, and explain how the results have been used to inform the inclusion of model-based seasonal “enhanced” ratings in the network planning process.
