1. Augmentation/Addition of Distribution Transformers
Distribution transformers have to be augmented by installing additional transformers or increasing the capacity of the transformer while the maximum demand on the transformer is near its rating. It is all the time better to add a transformer compare to augment. Therefore, it might become expedient to augment in view of space constraints or right of way considerations.
2. Relocation of Distribution Transformers at Load Centres
The location of transformers and category of transformers within the distribution system is strategically decided to ensure in which losses are kept inside optimum limits. Often distribution transformers are not located centrally along with respect to the consumers. Accordingly, the farthest consumers acquire an extremely low voltage even though reasonably good voltage levels are managed at the transformers' secondary. This again leads to higher line losses.
In order to decrease the voltage drop in the line to the farthest consumers, the distribution transformer should be located at the load centre to remain voltage drop inside permissible limits.
