Experiment 45 Three-Phase Circuits To study the relationship between voltage and current in three-phase circuits. To learn how to make delta wye connections. To calculate the power in three-phase circuits. DISCUSSION Students tend to approach three-phase circuits with a certain apprehension which is not at all justified. Three-phase circuits, in the majority of cases, are symmetrical. They consist of three identical branches, each of which has the same impedance. Each of these branches can be treated exactly like a singlephase circuit. Consequently, three phase circuits are not necessarily harder to work with than single-phase circuits. Unbalanced three-phase circuits represent an unnatural condition. Circuit analysis becomes somewhat difficult and will not be covered in this manual. Three-phase systems are usually connected by either a delta or a wye configuration. Each of connections has definite electrical characteristics the designations delta wye derived from the method of connection. EQUIPMEM REQUIRED Refer to the Equipment Utilization Chart, in Appendix A of this manual, to obtain the list of equipment required to perform this exercise. PROCEDURE CAUTION! High voltages are present in this Experiment1 Do not make or modify any banana jack connections with the power on unless otherwise specMedl 1. a. Using your Power Supply AC Vottmeter connect the circuit shown in Figure 45-1.
