Phase-shifting transformer

PST can prevent thermal overload of transmissionline and improve stability of power system, By controlling the power flow between different networks, for parallel long distance overhead-lines or for parallel cables, PST enables capacity increase of original transmission system, on top of that, compared with Flexible Alternative Current Transmission Systems (FACTS) a PST is very often the better economic approach to power flow management.
