Air-core Reactors
GE Vernova’s air-core reactors (ACR) provide a linear response of impedance versus current which is essential for numerous applications. GE Vernova’s reactors consist of aluminum or copper conductors, which are insulated with first class insulation materials. In encapsulated design, the conductors are mechanically immobilized and encapsulated by epoxy impregnated fiberglass, which assure high hygroscopic characteristic and long service life.

Series Application
Challenge
Integration of new power plants, transmission lines, power transformers and capacitor banks typically increases the normal, transient and short-circuit currents of the transmission and distribution networks. These new current levels exceed the current carrying capabilities of existing equipment.
Solution
GE Vernova’s series reactors provide a cost-effective solution to limit and/or reduce the excessive current levels under normal, transient and short time conditions, assuring quality, reliability and continuity of the power supply.
Shunt Application
Challenge
Transmission and distribution systems operating at low loading levels cause voltage increases in busbars and lines, resulting in insulation failures of the equipment on the grid and overall system instability.
Solution
GE Vernova’s shunt reactors provide system voltage control, operational flexibility, stability and reliability assuring long equipment life and continuity of power supply.
Iron-core Reactors
HV iron-core reactors are connected in series with the capacitor units to form a series resonant circuit with very low impedance. GE Vernova’s line of iron-core reactors are ideal for a variety of applications including capacitor banks formed by several steps, several capacitor banks connected in the same busbar, and capacitor bank installations with risk of resonance or with presence of harmonics.
Key benefits
- Reactive power compensation (power factor correction) in networks with harmonics
- Reduction of inrush currents that flow from step to step of the capacitor banks when switched
- Avoiding the risk of resonance as the LC circuit is having a resonance frequency below the first existing harmonic
- Decrease the level of harmonic distortion, as the circuit is also having a certain tuning frequency at which the branch will offer low impedance path for harmonic currents
Applications for renewable generation, wind and solar farms:
- Shunt reactors (up to 500kV)
- Short-circuit current-limiting reactors (up to 800kV)
- Tuning reactors for harmonic filters and MSCDN
- Damping reactors for shunt capacitor banks
Applications for FACTS, HVDC LCC and VSC, and transmission and distribution substations:
- Thyristor-controlled and thyristor-switched reactors for SVC
- Phase-reactors for STATCOM
- Tuning/blocking reactors for AC/DC, harmonic filters and MSCDN
- Damping reactors for TSC and shunt banks
- Smoothing and valve reactors for HVDC
- Shunt reactors (up to 500kV)
- Short-circuit current-limiting reactors (up to 800kV)
- Power-flow control reactors
- Neutral grounding reactors
Applications for buildings and cities, oil and gas, and industry and infrastructure:
- Shunt reactors (up to 500kV)
- Short-circuit current-limiting reactors (up to 800kV)
- Tuning reactors for harmonic filters and MSCDN
- Damping reactors for shunt capacitor banks
- Arc-furnace reactors
- Motor-starting reactors
- Laboratory reactors (special applications)
