6.7 Procedures 1. Connect the three-phase transformer as shown in the figure 6.1 2. Turn on the power supply. Gradually Increase the control knob so that the line currents will read .409A. The resistive load should be on its off position to have a zero load. 3. Open the resistive load using table below for purely resistive load TRANSFORMER SECONDARY LOADS TRIALS LOAD 1 LOAD 2 LOAD 3 1 300 ohms 300 ohms 300 ohms 2 600 ohms 600 ohms 600 ohms 3 1200 ohms 300 ohms 600 ohms 4 300 ohms 300 ohms 1200 ohms 4. Measure the Line and Phase voltages and complete table 6.1 for primary and secondary side 5. Measure the Line and Phase current and complete table 6.2 for primary and secondary side. 6. Return the current to zero and turn off the power supply.
