ABSTRACT:
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.degree., 120.degree. or 180.degree.. 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.degree. to operation with a phase angle of 120.degree. or 180.degree..
