English to Swedish Tech/Engineering Electronics / Elect Eng

Hello,

I am translating a MECB Manual from English to Swedish and I am having difficulty with the following term:

"Detuning reactor"

Here is some context:

"Detuning reactors (if applicable only)
The MECB system come equipped with detuning reactors installed in series with the capacitors. These reactors help to prevent the risk of parallel resonance between the network and the capacitor bank and should be fitted when harmonics are present on the network."

I would really appreciate some help. Thanks in advance!
