RESI® – Resonance Elimination Harmonic Filters
What is a resonance in electrical networks?
Any electrical networks consist of inductance and capacitance. Elements such as choke, transformer, motor loads represent inductive components (L), whereas cables, capacitor banks, input filter of inverters, etc. represents capacitive components (C). Therefore, any electrical network or LC Circuit involving inductor and capacitor forms a resonance at a resonant frequency which creates huge swinging of currents within that electrical network.
What causes resonance in electrical networks?
⦁ Commutation notches
⦁ Switching frequencies of power electronics converters
⦁ Longer cables
⦁ Multiple EMC filters of VFD Loads
⦁ Capacitor banks, APFCs without reactor or choke
How does a resonating waveform look like?
Solution – RESI® Resonance Elimination Harmonic Filter
RESI® is a high-pass filter which is designed or tuned to damp the resonance at that particular resonant frequency. RESI® systems are available up to larger ratings when attenuating the effects of commutation sags through high-power converters is necessary.
