Problem #1 The VLN at the terminals of a balanced three-phase source is 2.4 kV. The load is Y- connected and has an impedance of 16+j12 22/6. The load is fed from a line having an impedance of 0.12 + j0.96 2/b. a) Draw the single-phase equivalent circuit. b) Calculate the line current (Ia) c) Calculate the line-to-neutral voltage at the load (Van) d) Calculate the line-to-line voltage at the load (Vab)

A balanced three-phase, negative sequence, Y-connected generator is connected to a three-phase balanced Y-connected load. The generator has an impedance of 1.5-j1.25 Q/phase. The impedance of the line connecting the generator to the load is 2.5+jl1.25 0/phase. The phase "B" load voltage is 1520° kV. The impedance of each phase of the Y-connected load is 60-j80 Q/phase. Calculate phase voltages \(V_{an}\) at the generator. \(V_{an}=\) Volts

A single phase, unity power factor load takes 90 Amps at 10 kV. Using a base voltage of 65 kV and base kilovolt amperes of 4475 kVA. Find the base current, base impedance, base power, per unit current and per unit voltage of the load.
