A balanced load with ZR = ZB = ZY = ……<00 Ω was supplied a three phase 50 Hz, 100 V between line (balanced source). A fault on phase ‘B’ causes an open circuit, which unbalanced the load as shown in Figure 4. Similarly, a fault on the load of phase ‘Y’ cause a short-circuit, which unbalanced the load as shown in Figure 5. Using complex notation determine and analyse the individual phase currents and the neutral current in both figure.
