Power system operation involves many switching functions that may inject currents with different harmonic resonance frequencies. Mitigation of such harmonic sources is vital. There is no safe rule to avoid such resonant currents, but resonances above 1000 Hz will probably not cause problems except interference with telephone circuits.. This means the …
Therefore, the filter can only use polar capacitors, and the polar capacitance is irreversible. Usually, electrolytic capacitors are above 1 MF; best used in coupling, decoupling, power supply filtering, etc. Non-polar capacitors are mostly below 1 MF, which only involves resonance, coupling, frequency selection, current limiting, etc.
