Unformatted text preview: Irwin, Basic Engineering Circuit Analysis, 9/E 11.46 In a balanced three—phase system, the source has an nine—phase sequence and is connected in delta. There are two parallel owe—connected loads. The phase impedance of load 1 and load 2 is 4 + _.i4 [1 and 10 + j-fl- [1, respectively. The line impedance connecting the source to the loads is 0.3 + fill 11 If the current in the n phase of load 1 is I AMI = 101.320: A rnts, find the delta currents in the source.
