It is connected in parallel across the line to increase voltage by reducing the inductive VArs and is generally a lagging power factor. To correct the power factor appropriate for the substation load, VAr due to computation is reduced by using a lagging power factor, while the leading power factor substation increases VAr supply, which may reduce the quality of real power supply. Balanced capacitor banks are installed on each phase of the 3φ power system for effective power factor correction. Capacitors can be switchable automatically, depending on voltage degradation.
4 Phase Shifter or Regulating Transformer The phase-shifter transformer is a special type of regulatory transformer that is primarily used to alter the current and voltage phase angles in a transmission or distribution system. It is used to control power flows and losses within power networks. 15 Three-phase regulating transformer. 16 Network representation of the static phase-shifter transformer. system. 16. The physical device consists of two sets of windings representing a booster transformer and a magnetizing transformer.
