The magnitude of the line-to-line voltages at the source side and at the load side are 120 and 110 kV, respectively. If the power factor of the load is 0.90 lagging, determine (a) the currents (magnitude and angle) and voltages (magnitude and angle) of the 30 load. (Hint: Voltage at the source side and the load side have given magnitude but different angles. Assume the load is Y-connected and use its Van as the reference.) II. For Figure 2: The 3-phase load is connected to a balanced 2300V, abc source. In doing this, 3 conductors are used with the conductors having an impedance of Z₁ = 0.5+j2 ohms each. After connection, the load receives 120 kVA at 0.6 power factor lagging. Determine the line currents. (Hint: Assume the load is Y-connected and use single-line representation.)
