Ungrounded Delta 480V/3-Phase/3-Wire - Mike Holt's Forum
Mar 17, 2017I have a project where the existing pad mounted utility transformer is configured as delta-delta. The utility company says it is an un-grounded delta secondary at 480V/3-phase/3-wire system. I asked them to take voltage readings between phase-phase and phase-ground just to make sure it is an un-grounded delta secondary.
Easy understanding of 3-phase transformer connections
Easy understanding of 3-phase transformer connections - Delta–Delta, Wye–Wye, Delta–Wye and Wye–Delta (on photo: Jefferson Electric transformer) While three-phase devices are usually the more cost-effective option, the single-phase option provides more versatility and can be attractive from a reliability and maintenance standpoint .

Three Phase Transformer Connections and Basics
In a delta connected ( Dd ) group of transformers, the line voltage, V L is equal to the supply voltage, V L = V S 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[PDF]
240/120 Four-Wire Delta Connection Transformers

Delta-Delta Transformer Connection Overview
Disadvantages of Delta-Delta Transformer Connection. Due to the absence of neutral point it is not suitable for three phase four wire system. More insulation is required and the voltage appearing between windings and core will be equal to full line voltage in case of earth fault on one phase.
