Figure 2-18 shows a one-line diagram of a small 480-V industrial distribution system. The power system supplies a constant line voltage of 480 V, and the impedance of the distribution lines is negligible. Load 1 is a A-connected load with a phase im- pedance of 130° 2, and load 2 is a Y-connected load with a phase impedance of 5L-36.87° N. (a) Find the overall power factor of the distribution system. (b) Find the total line current supplied to the distribution system. Figure 2-18 I The system in Example 2-3. Bus A Load Delta connected 1 Z, = 10230°O Load Wye connected 480 V three-phase 2. Z, = 52-36.87°2

Question
For this kind a problem, how do you know how the voltage source is configured ( wye or delta). The problem start getting the phase current for phase 1 and 2 , but do we have to pretend that voltage source to delta load is connected like y-delta to convert the voltage to delta source? Or how does it work?
