A three-phase transmission line has resistance and inductive reactance of 25V and 90V, respectively. With no load at the receiving end, a synchronous compensator there takes a current lagging by 90; the voltage is 145 kV at the sending end and 132 kV at the receiving end. Calculate the value of the current taken by the compensator.
When the load at the receiving end is 50MW, it is found that the line can operate with unchanged voltages at the sending and receiving ends, provided that the compensator takes the same current as before, but now leading by 90. Calculate the reactive power of the load
