Shunt Reactors are designed for reactive power compensation and voltage control in transmission systems.

Shunt reactors are applied in high-voltage networks to absorb reactive power, control overvoltages, and stabilize voltage profiles along transmission lines. 

Each unit is engineered according to system electrical parameters, short-circuit levels, load conditions, and applicable technical standards. 

Role in System Stability

Shunt reactors are connected in parallel to transmission lines in order to: 

  • Absorb reactive power under low-load conditions 
  • Reduce overvoltages 
  • Improve voltage profile along long transmission corridors 
  • Support stability in interconnected and large-scale networks 

Their application is essential in extended transmission systems or grids with high operational variability. 

Applications
  • Transmission substations 
  • Long-distance transmission lines 
  • Regional interconnections 
  • Networks with high renewable energy integration 
Operating Principle

A shunt reactor operates by absorbing reactive power when connected in parallel to the grid, contributing to the balance between active and reactive power and maintaining voltage within defined system limits.
