What are the elctrical relationships in terms of voltage & current between delta and star connections?
With a balanced three phase load, the voltage across each branch of a delta connected load is the line to line voltage and the current in each branch is the line current multiplied by the square root of three. For a wye connected load, the voltage across each branch, the line to neutral voltage, is the line to line voltage divided by the square root of three and the current in each branch is the line current.
