Shunt Reactor
Rated Voltage: Up to 500 kV
Functional Overview
Connected in parallel to power systems to:
1.Compensate capacitive VARs on lightly loaded transmission lines/underground cables
2.Maintain voltage stability within ±2% of nominal during load variations
3.Improve system efficiency by reducing dielectric losses (up to 30% energy savings)
4.Prevent overvoltage conditions during load rejection or Ferranti effect scenarios
