Three balanced 3 phase loads are connected in parallel. Load 1 is Y-connected with an impedance of 400 + j300Ω/φ, Load 2 is ∆–connected with an impedance of 2400 −j1800Ω/φ and Load 3 is rated at 172.8 + j2203.2kVA. The loads are fed from a distribution line with an impedance of 2 + j16Ω/φ. Magnitude of line–to–neutral voltage at the load end of the line is 24√3 kV. The frequency of operation is 50Hz. (a) Calculate the line currents and the phase currents of the loads. (b) Calculate the total complex power at the receiving end of the system. (c) Calculate the total complex power at the sending end of the line
