Adjust the reactive loads such that all the dials are set fully lagging (counter-clockwise). Set the variable resistance to 1000 per phase. Use an oscilloscope to measure voltages and currents throughout the experiment. 2) Bring the variable voltage up to 120 V line-neutral. 3) Measure the current in each phase and neutral of the reactive load. Adjust the reactive loads so that the current is the same in each phase and the neutral current is nearly zero. 4) Measure and record phase A line-neural voltage (Vxx), line current magnitude (Ixz) and phase (Lxz), each reactive current's magnitude (lax. Iux. Lox), the reactive current neutral magnitude (Ixx), and the resistive current neutral magnitude (Isa). Use Vax as the phase reference for these measurements. 5) Repeat steps 3 and 4 for several settings of reactive load.
