It has already been shown in Section 9.6 that a three phase star-connected load can be replaced by an equivalent delta-connected load. Thus, the star load of Fig. 9.38(a) can be replaced by equivalent delta as shown in Fig. 9.38(b), where the impedances in each phase is given by touchscreen device manager windows 10WebBalanced Three Phase System-Star Connected Load. Figure 22.2 (a) shows a three-phase, three wire system supplying power to a balanced three phase star connected load. The phase sequence RYB is assumed. In star connection, whatever current is flowing in the phase is also flowing in the line. The three line (phase) currents are IR’ IY and IB. potted dwarf lime tree dropping leavesWebSequence Impedance and Networks of Load: For a star-connected load with isolated neutral, there is no path for the flow of zero-sequence currents and the star point of the load will not be connected to the reference bus, as shown in Fig. 3.15.
