  • Voltage control system
    Patent number: 9618950
    Abstract: According to an embodiment, the invention provides a voltage control system for medium voltage applications. The voltage control system provides a booster-transformer and a feeder-transformer, each of the booster-transformer and the feeder-transformer having a respective primary winding and a secondary winding, wherein the secondary winding of the feeder-transformer is electrically connected with the primary winding of the booster-transformer by an intermediate circuit. The voltage control system also includes a connection device configured to connect the secondary winding of the booster transformer with an electrical energy supply network in order that the secondary winding of the booster transformer is connected in series with a transmission line having a voltage that is to be controlled.
