Three Phase Transformer Connections and Basics

Apr 13, 2021  In a delta connected ( Dd ) group of transformers, the line voltage, V L is equal to the supply voltage, V L = V S.But the current in each phase winding is given as: 1/√ 3 × I L of the line current, where I L is the line current. One disadvantage of delta connected three phase transformers is that each transformer must be wound for the full-line voltage, (in our example above 100V) and for ...
