Hi,

imagine we have the following circuit shown in the figure below. There are installed a passive filter to filter the 5th harmonic. Now, after installation this creates a parallel path with a generator connected, let's say that this parallel circuit has a resonance frequency at the 7th harmonic. Then it turns out that some load further away causes 7th harmonic currents to flow and thus exciting the parallel resonance circuit.

- Would this cause Z to go to infinity in theory assuming ideal components and thus stop the flow of 7th harmonic currents from A to B shown in the figure below?
- Would fundamental currents and other harmonic currents except for the 7th be able to flow between A and B?
