SVC Solutions

SVC (static VAr compensator) solutions are power factor correction equipment that balances the reactive power of each phase separately by switching single-phase shunt reactors in steplessly with an electronic driver. They are used to complement a capacitor-stepped power factor correction panel in facilities where reactive power changes quickly, is unevenly distributed across the phases or shifts toward capacitive. The system consists of three parts: an SVC-capable reactive power relay, an inductive load driver and the shunt reactors connected to the driver. Entes SR and Tense SRL drivers are listed with total ratings such as 5 kVAr, 10 kVAr, 20 kVAr and 30 kVAr, Tibcon modules with per-phase ratings such as 3x3.33 kVAr and 3x10 kVAr, and Entes 230 V single-phase reactors with values such as 1.66 kVAr, 3.33 kVAr and 10 kVAr. Match the driver's per-phase driving capacity to the power of the reactors to be connected; compare your relay's SVC support, the permitted fuse current and the recommended cable cross-section according to the manufacturer data. This category contains drivers and reactors; SVC-compatible relays are in the reactive power control relays category.

How to choose SVC Solutions

SVC (static VAr compensator) solutions are power factor correction equipment that balances the reactive power of each phase separately by switching single-phase shunt reactors in steplessly with an electronic driver. They are used to complement a capacitor-stepped power factor correction panel in facilities where reactive power changes quickly, is unevenly distributed across the phases or shifts toward capacitive.

  • Take reactive power demand and harmonic distortion levels from site measurements or project calculations.
  • Compare kVAr step sizes, rated voltage and step count against the compensation panel layout.
  • Select capacitor duty contactors, harmonic filter reactors and discharge resistors together with the capacitor bank.
