Effect of poor designing of distribution system case study Tanzania electric supply company network

The Tanzania Electric supply company (TANESCO) distribution feeder network has been analyzed by using the Simpow simulation software in which it has been found that there is a problem of overloading of distribution transformers and distribution lines as well as load phase imbalance. Recommendations on how to improve overloading of transformers and distribution lines have been suggested. The suggested method also reduces power loss in the feeder by 20 percent. Lastly the paper recommends that the loads should be redistributed equally to each phase to alleviate the unsymmetrical problems.
