Please answer quickly "In series-connected ac circuit, the total voltage across the circuit is always equal to the sum of the magnitude (only) of the individual voltage across each element." True False The power factor is equal to cosine of the phase difference. True False A leading power factor means that the circuit is predominantly capacitive in nature. True False "Since most loads are resistive in nature (e.g. motors), improvement of power factor is done by connecting capacitor banks or a synchronous condenser " True False

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.
