Calculating the residual life of insulation in transformers connected to solar farms and operated at high load.

In Australia, similarly to other countries, the grid was designed and constructed to transport energy from large fossil-fuelled generators to load centers. There has been a very rapid uptake of large renewable generation and their lifecycle costs are continuing to fall. These solar farms are generally located in sparsely populated areas where large packets of land are available. However, the grid infrastructure in these areas has limitations as it was not designed to support large power flows. [ABSTRACT FROM AUTHOR]
