4. INTRODUCTION This s a small note discussing about one of compensators that is mostly used in power system for improving quality of power transmitted form source to load. here in this paper its concentrated on the very basic of this compensator telling answer for why? What? When? How? etc.. As an electrical engineer in our day to day life we are dealing with real and reactive power which can determine the quality of power transmitted from source to load.

5. Literature Review static synchronous compensator, is a regulating device used on ac current electricity transmission networks. It is based on a power electronics voltage source converter and can act as either a source or sink of reactive AC power to an electricity network. If connected to a source of power it can also provide active AC power It is a member of the FACTS family of devices.

10. What Is GTO? A gate turn-off thyristor (GTO) is a special type of thyristor, which is a high-power semiconductor device. It was invented at General Electric. GTOs, as opposed to normal thyristors are fully controllable switches which can be turned on and off by their third lead, the GATE lead.
