Distribution transformer models for branch current based feeder

This paper proposes a new method to include distribution transformers in feeder analysis. The proposed method tailors the transformer models specifically for the branch current based feeder analysis method.

Introduction to Power Distribution Systems

At a distribution substation, a substation transformer takes the incoming transmission-level voltage (35 to 230 kV) and steps it down to several distribution primary circuits, which fan out from the substation.
