How will the proposed 66kV substation work?
The proposed substation will have 66kv high voltage incoming line with several 11kv feeder lines going out. The incoming 66kv voltage will be stepped down to 11kv voltage through two 23MVA transformers [1]. The stepped down voltage will be evacuated and sent through the existing distribution line via underground cable.
