You have been privately contacted to rewire a site. During a visit, you observed that the building receives a 400V, 60Hz, star-connected, three-phase supply from the utility. There are also several three-phase equipment that require a 230V three-phase supply. You have decided to utilize three single-phase, dry type transformers to step down the building’s incoming supply to a 230V, delta-connected supply for the equipment. All the three-phase machinery can be modelled as an equivalent balanced three-phase star-connected load with a resistance and inductance of 0.5Ω and 0.16mH respectively per phase. Some preliminary calculations and analysis are required before starting the wiring design.Draw a labelled diagram of the entire three phase system clearly showing all known voltages (phase and line values) and the three phase configurations of all components.
