A phase shifter comprises a three-phase transformer and a reactor to obtain two three-phase output voltage sets, the phase angle therebetween being set equal to 0 DEG , 120 DEG or 180 DEG . Depending on the load, the proposed phase shifter makes it possible, with its transformer or reactor control windings shorted, to switch over a controlled power transmission system of high power-carrying capacity from operation with a phase angle of 0 DEG to operation with a phase angle of 120 DEG or 180 DEG .
