Jump to key moments of Three equal impedances Z = magnitude of 10, argument pf -45degrees are connected in Y - formation across a 250V line. 1. Draw the labelled wiring diagram and sketch the phasor diagram of voltages and current from the phasor diagram. 2.Convert the Y- formation to a delta formation and obtain its phasor diagram of voltages and current. 3.Compare the phasor diagrams
