50 - Balanced Star Delta 3 - Phase Circuit In this video, we are going to consider the balanced star delta three phase circuit. A balanced star delta circuit is a circuit which consist of a balanced star connected source and balanced delta connected load. There is no neutral connection between the source and the load. To solve a question like this, we transform the delta connected load to a star connected load. Next we find the phase currents, line currents and line voltage if not given. Star Configuration VL = root(3)*Vp IL = Ip Delta Configuration VL = Vp IL = root(3)*Ip S = root(3)*VL*IL P = root(3)*VL*IL cos phi Q = root(3)*VL*IL sin phi 00:00 - Balanced Star Delta System/Circuit 03:17 - Example 1 13:57 - Example 2 20:20 - Example 3
