High voltage reactors are special magnetic components used in MV and HV power systems to

• reduce harmonic distortion,

• prevent resonance and

• limit transient effects such as inrush current.
   

With high inductance stability, low losses and thermal endurance, Enersolix HV reactor solutions ensure long service life for compensation systems, filters and capacitor banks.
 

Reactor Types and Functions

Harmonic filter reactors: connected in series with capacitor banks, they create a high impedance at harmonic frequencies and so prevent harmonics spreading into the network.

They are usually selected with detuning factors of 5.67% / 7% / 14%.
They reduce the risk of resonance and extend capacitor life.
 

Current-limiting reactors: limit the peak inrush currents that occur when capacitor banks are switched in.

• They protect equipment such as circuit breakers, contactors and capacitors.

• They are especially critical in back-to-back switching.
