Q=65
For each phase, the star connected load formed by the series connected elements whose values are Ry = 8Ω and Ly = 0.1H is connected to the star connected three phase voltage source with the line with the impedance Z = 3 + j5 Ω for each phase. What should be the effective value of the voltage source so that the load can absorb reactive power of total Q kVAr? What would be the tension at the load ends in this case? Carry out the calculations after drawing the circuit. The mains frequency is 50 Hz.
