Current transformer model in distribution box
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.
Electrical Sensors: Potential Transformers (PTs) and Current

How to use the current transformer in the distribution box
Install in the correct direction: The L1 terminal of the primary side of the current transformer should be connected to the power inlet wire, and the L2 terminal should be connected to the load...

Useful in voltage upgrades: a 2.4kV delta feeder can be converted to 4W-Y (4.16kV) by reconnecting the same transformers from DD to YY (assuming power rating is OK)
MODELING DISTRIBUTION TRANSFORMERS FOR INRUSH
In this paper, a single-phase distribution transformer model is developed and presented based on transformer topology with the concern for its inrush currents. The modeling is suitable with what
