I'm trying to understand the different electrical systems between wye and delta and the variety of voltages that these system can derive . I recently have worked in a factory were the system was a corner-grounded delta , a phase to ground read zero so that has to be the grounded leg . Phase to phase read 240v, b, c , phase to ground read 240. so if you neaded to supply a piece of equipment with 240 could you only bring phase b or do you still have to bring both phases. What is the advantage of having a corner grounded delta ? Do they still supply corner grounded deltas? Is a center tap delta the system with the high leg? Can someone please list the voltages of wye and deltas so I can study and recognize each system. Thank you for your time
