Static Var Compensation (SVG)

SVG series IGBT switching compensation systems consist of high technology IGBT drivers and modules. It can perform both inductive reactive and capacitive reactive compensation in both directions.

Thanks to the HMI panel and power measurement/ control cards on the SVG series compensation systems, it processes the measurement data taken, drives the high frequency IGBT inverters, and performs the compensation process simultaneously without delay and with perfect sensitivity.

SVG series compensation systems are designed for facilities with fast load change, where the reactive limit is very important, and thanks to high speed and sensitive IGBT inverter switching, it injects bidirectional reactive power into the circuit in accordance with the load change, balanced or unbalanced, inductive or capacitive. It perfectly performs reactive power compensation in the direction


  • Immediate response to rapid and sudden load changes
  • Easy installation and operation thanks to its modular design
  • Easy power increase thanks to its modular structure
  • Thanks to its modular structure, easy material and equipment change, it allows backup
  • Switching and compensation without causing transients and harmonics
  • One-to-one independent intervention to the balanced or unbalanced load for 3 phases, 3 phase load balancing
