Question A three-phase generator supplies two three-phase loads. The 2.4 kV generator is rated at 180 kVA. The per-unit impedance of Load 1 is ZLoad1=80%+j75% and for Load 2 is ZLoad2=70%+j25% on 200 kVA and 2.5 kV bases. (a) Draw the equivalent circuit. (b) Determine the ohmic value of the impedances. (c) Calculate the source current in amperes and in percent if the generator operating voltage is 3.8 kV (line-to-line) and a reactance of X=125% is connected in series with the generator voltage. Answers : (b) Zload1 = 25 + j23.4 Ω , Zload2 = 21.9 + j7.8 Ω ; (c) Igen = 45.3 A = 97.99% looking only for step by step solution (No chegg)
Question
A three-phase generator supplies two three-phase loads. The 2.4 kV generator is rated at 180 kVA. The per-unit
impedance of Load 1 is ZLoad1=80%+j75% and for Load 2 is ZLoad2=70%+j25% on 200 kVA and 2.5 kV bases.
(a) Draw the equivalent circuit.
(b) Determine the ohmic value of the impedances.
(c) Calculate the source current in amperes and in percent if the generator operating voltage is 3.8 kV (line-to-line) and a reactance of X=125% is connected in series with the generator voltage.
Answers :
(b) Zload1 = 25 + j23.4 Ω , Zload2 = 21.9 + j7.8 Ω ; (c) Igen = 45.3 A = 97.99%
