A 3 phase 3 wire ac circuit is fed from a 50 HZ system with line voltage of 400 V. A balanced load is connected to it. Calculate for the 4 cases given below the current in the lines connecting the source and the load, the source phase currents and the load phase currents.
Case 1: The source is star connected and the load is a balanced star connected impedance of 10 Ohms in each arm
Case 2: The source is star connected and the load is a balanced Delta connected impedance of 10 Ohms in each arm
Case 3: The source is Delta connected and the load is a balanced star connected impedance of 10 Ohms in each arm
Case 4: The source is Delta connected and the load is a balanced Delta connected impedance of 10 Ohms in each arm.
Case 1: The source is star connected and the load is a balanced star connected impedance of 10 Ohms in each arm
Case 2: The source is star connected and the load is a balanced Delta connected impedance of 10 Ohms in each arm
Case 3: The source is Delta connected and the load is a balanced star connected impedance of 10 Ohms in each arm
Case 4: The source is Delta connected and the load is a balanced Delta connected impedance of 10 Ohms in each arm.
