Hello,
In some medium voltage circuits feeding motors, there are some capacitors installed.
These capacitors are receiving some harmonics in excess, so we think that some reactors should be installed "in series" with them, to tune the circuit and avoid the resonances.
We already analized and the resonances are caused on the 13th component, the question is:
The reactors should be choosen to reject this 13th component?
I ask this because, contacting some manufacturers, they typically choose the reactor at 6% of the capacitive reactance value.
If we do that, the reactor rejects at 4th component and the 13th resonance keeps in the circuit.
Any clue, reference or recommendation will be thank!
