LV Iron Core Shunt Reactors

Overview

Iron Core Shunt Reactors absorb reactive power to improve the efficiency and voltage stability of electrical power systems.

These reactors provide inductive compensation for the capacitive reactive power generated by long transmission lines and underground cable networks, increasing active power transfer capability while preventing overvoltages. They can be connected directly to transmission lines or to the tertiary winding of power and distribution transformers.

Typical Applications

Iron Core Shunt Reactors are primarily used for reactive power compensation of long or lightly loaded transmission lines and underground cables in:

  • Wind Farms
  • Metro (Subway) Systems
  • Urban Distribution Systems
  • Industrial Zones
  • University Campuses
  • Electrical Substations
